How to Write the “Why Computer Science?” Essay

What’s covered:, what is the purpose of the “why computer science” essay, elements of a good computer science essay, computer science essay example, where to get your essay edited.

You will encounter many essay prompts as you start applying to schools, but if you are intent on majoring in computer science or a related field, you will come across the “ Why Computer Science? ” essay archetype. It’s important that you know the importance behind this prompt and what constitutes a good response in order to make your essay stand out.

For more information on writing essays, check out CollegeVine’s extensive essay guides that include everything from general tips, to essay examples, to essay breakdowns that will help you write the essays for over 100 schools.

Colleges ask you to write a “ Why Computer Science? ” essay so you may communicate your passion for computer science, and demonstrate how it aligns with your personal and professional goals. Admissions committees want to see that you have a deep interest and commitment to the field, and that you have a vision for how a degree in computer science will propel your future aspirations.

The essay provides an opportunity to distinguish yourself from other applicants. It’s your chance to showcase your understanding of the discipline, your experiences that sparked or deepened your interest in the field, and your ambitions for future study and career. You can detail how a computer science degree will equip you with the skills and knowledge you need to make a meaningful contribution in this rapidly evolving field.

A well-crafted “ Why Computer Science? ” essay not only convinces the admissions committee of your enthusiasm and commitment to computer science, but also provides a glimpse of your ability to think critically, solve problems, and communicate effectively—essential skills for a  computer scientist.

The essay also gives you an opportunity to demonstrate your understanding of the specific computer science program at the college or university you are applying to. You can discuss how the program’s resources, faculty, curriculum, and culture align with your academic interests and career goals. A strong “ Why Computer Science? ” essay shows that you have done your research, and that you are applying to the program not just because you want to study computer science, but because you believe that this particular program is the best fit for you.

Writing an effective “ Why Computer Science ?” essay often requires a blend of two popular college essay archetypes: “ Why This Major? ” and “ Why This College? “.

Explain “Why This Major?”

The “ Why This Major? ” essay is an opportunity for you to dig deep into your motivations and passions for studying Computer Science. It’s about sharing your ‘origin story’ of how your interest in Computer Science took root and blossomed. This part of your essay could recount an early experience with coding, a compelling Computer Science class you took, or a personal project that sparked your fascination.

What was the journey that led you to this major? Was it a particular incident, or did your interest evolve over time? Did you participate in related activities, like coding clubs, online courses, hackathons, or internships?

Importantly, this essay should also shed light on your future aspirations. How does your interest in Computer Science connect to your career goals? What kind of problems do you hope to solve with your degree?

The key for a strong “ Why This Major? ” essay is to make the reader understand your connection to the subject. This is done through explaining your fascination and love for computer science. What emotions do you feel when you are coding? How does it make you feel when you figure out the solution after hours of trying? What aspects of your personality shine when you are coding? 

By addressing these questions, you can effectively demonstrate a deep, personal, and genuine connection with the major.

Emphasize “Why This College?”

The “ Why This College? ” component of the essay demonstrates your understanding of the specific university and its Computer Science program. This is where you show that you’ve done your homework about the college, and you know what resources it has to support your academic journey.

What unique opportunities does the university offer for Computer Science students? Are there particular courses, professors, research opportunities, or clubs that align with your interests? Perhaps there’s a study abroad program or an industry partnership that could give you a unique learning experience. Maybe the university has a particular teaching methodology that resonates with you.

Also, think about the larger university community. What aspects of the campus culture, community, location, or extracurricular opportunities enhance your interest in this college? Remember, this is not about general praises but about specific features that align with your goals. How will these resources and opportunities help you explore your interests further and achieve your career goals? How does the university’s vision and mission resonate with your own values and career aspirations?

It’s important when discussing the school’s resources that you always draw a connection between the opportunity and yourself. For example, don’t tell us you want to work with X professor because of their work pioneering regenerative AI. Go a step further and say because of your goal to develop AI surgeons for remote communities, learning how to strengthen AI feedback loops from X professor would bring you one step closer to achieving your dream.

By articulating your thoughts on these aspects, you demonstrate a strong alignment between the college and your academic goals, enhancing your appeal as a prospective student.

Demonstrate a Deep Understanding of Computer Science

As with a traditional “ Why This Major? ” essay, you must exhibit a deep and clear understanding of computer science. Discuss specific areas within the field that pique your interest and why. This could range from artificial intelligence to software development, or from data science to cybersecurity. 

What’s important is to not just boast and say “ I have a strong grasp on cybersecurity ”, but instead use your knowledge to show your readers your passion: “ After being bombarded with cyber attack after cyber attack, I explained to my grandparents the concept of end-to-end encryption and how phishing was not the same as a peaceful afternoon on a lake. ”

Make it Fun!

Students make the mistake of thinking their college essays have to be serious and hyper-professional. While you don’t want to be throwing around slang and want to present yourself in a positive light, you shouldn’t feel like you’re not allowed to have fun with your essay. Let your personality shine and crack a few jokes.

You can, and should, also get creative with your essay. A great way to do this in a computer science essay is to incorporate lines of code or write the essay like you are writing out code. 

Now we will go over a real “ Why Computer Science? ” essay a student submitted and explore what the essay did well, and where there is room for improvement.

Please note: Looking at examples of real essays students have submitted to colleges can be very beneficial to get inspiration for your essays. You should never copy or plagiarize from these examples when writing your own essays. Colleges can tell when an essay isn’t genuine and will not view students favorably if they plagiarized.

I held my breath and hit RUN. Yes! A plump white cat jumped out and began to catch the falling pizzas. Although my Fat Cat project seems simple now, it was the beginning of an enthusiastic passion for computer science. Four years and thousands of hours of programming later, that passion has grown into an intense desire to explore how computer science can serve society. Every day, surrounded by technology that can recognize my face and recommend scarily-specific ads, I’m reminded of Uncle Ben’s advice to a young Spiderman: “with great power comes great responsibility”. Likewise, the need to ensure digital equality has skyrocketed with AI’s far-reaching presence in society; and I believe that digital fairness starts with equality in education.

The unique use of threads at the College of Computing perfectly matches my interests in AI and its potential use in education; the path of combined threads on Intelligence and People gives me the rare opportunity to delve deep into both areas. I’m particularly intrigued by the rich sets of both knowledge-based and data-driven intelligence courses, as I believe AI should not only show correlation of events, but also provide insight for why they occur.

In my four years as an enthusiastic online English tutor, I’ve worked hard to help students overcome both financial and technological obstacles in hopes of bringing quality education to people from diverse backgrounds. For this reason, I’m extremely excited by the many courses in the People thread that focus on education and human-centered technology. I’d love to explore how to integrate AI technology into the teaching process to make education more available, affordable, and effective for people everywhere. And with the innumerable opportunities that Georgia Tech has to offer, I know that I will be able to go further here than anywhere else.

What the Essay Did Well 

This essay perfectly accomplishes the two key parts of a “ Why Computer Science? ” essay: answering “ Why This Major? ” and “ Why This College? ”. Not to mention, we get a lot of insight into this student and what they care about beyond computer science, and a fun hook at the beginning.

Starting with the “ Why This Major? ” aspect of the response, this essay demonstrates what got the student into computer science, why they are passionate about the subject, and what their goals are. They show us their introduction to the world of CS with an engaging hook: “I held my breath and hit RUN. Yes! A plump white cat jumped out and began to catch the falling pizzas. ” We then see this is a core passion because they spent “ Four years and thousands of hours ,” coding.

The student shows us why they care about AI with the sentence, “ Every day, surrounded by technology that can recognize my face and recommend scarily-specific ads ,” which makes the topic personal by demonstrating their fear at AI’s capabilities. But, rather than let panic overwhelm them, the student calls upon Spiderman and tells us their goal of establishing digital equality through education. This provides a great basis for the rest of the essay, as it thoroughly explains the students motivations and goals, and demonstrates their appreciation for interdisciplinary topics.

Then, the essay shifts into answering “ Why This College? ”, which it does very well by honing in on a unique facet of Georgia Tech’s College of Computing: threads. This is a great example of how to provide depth to the school resources you mention. The student describes the two threads and not only why the combination is important to them, but how their previous experiences (i.e. online English tutor) correlate to the values of the thread: “ For this reason, I’m extremely excited by the many courses in the People thread that focus on education and human-centered technology. ”

What Could Be Improved

This essay does a good job covering the basics of the prompt, but it could be elevated with more nuance and detail. The biggest thing missing from this essay is a strong core to tie everything together. What do we mean by that? We want to see a common theme, anecdote, or motivation that is weaved throughout the entire essay to connect everything. Take the Spiderman quote for example. If this was expanded, it could have been the perfect core for this essay.

Underlying this student’s interest in AI is a passion for social justice, so they could have used the quote about power and responsibility to talk about existing injustices with AI and how once they have the power to create AI they will act responsibly and help affected communities. They are clearly passionate about equality of education, but there is a disconnect between education and AI that comes from a lack of detail. To strengthen the core of the essay, this student needs to include real-world examples of how AI is fostering inequities in education. This takes their essay from theoretical to practical.

Whether you’re a seasoned writer or a novice trying your hand at college application essays, the review and editing process is crucial. A fresh set of eyes can provide valuable insights into the clarity, coherence, and impact of your writing. Our free Peer Essay Review tool offers a unique platform to get your essay reviewed by another student. Peer reviews can often uncover gaps, provide new insights or enhance the clarity of your essay, making your arguments more compelling. The best part? You can return the favor by reviewing other students’ essays, which is a great way to hone your own writing and critical thinking skills.

For a more professional touch, consider getting your essay reviewed by a college admissions expert . CollegeVine advisors have years of experience helping students refine their writing and successfully apply to top-tier schools. They can provide specific advice on how to showcase your strengths, address any weaknesses, and generally present yourself in the best possible light.

Long and Short Computer Essay

The term computer was once used to refer to a person who did computation, unlike today. The development of early prototypes that led to the modern computer is credited to many individuals throughout history. A series of breakthroughs, beginning with transistor computers and then integrated circuit computers, resulted in the development of transistor technology and the integrated circuit chip, causing digital computers to largely replace analogue computers. 

In this essay, we will discuss the various components and types of computers and talk about their uses in various fields.

Long Computer Essay in English

A computer is an electronic tool that manipulates data or information. It can store, retrieve, and process information. We can type documents, send emails, play games, and browse the Web using a computer. It can also be used to edit spreadsheets, presentations, and even videos, or create them. 

Early computers were conceived only as devices for calculating. Simple manual devices such as the abacus have helped individuals do calculations since ancient times. Some mechanical devices were built early in the Industrial Revolution to automate long, tedious tasks, such as guiding patterns for looms. In the early 20th century, more sophisticated electrical machines performed specialized analogue calculations. 

Common Components of Computers

All those parts of a computer that are tangible physical objects are covered under the term hardware. The hardware includes circuits, computer chips, graphics cards, sound cards, memory (RAM), motherboards, displays, power supplies, cables, keyboards, printers and "mice" input devices.

 There are five main hardware components: 

Input Devices: 

These are devices that are used to enter data/information in the central processing unit. Example- keyboard, mouse, scanner, document reader, barcode reader, optical character reader, magnetic reader etc.

Output Devices: 

These are devices that provide the processed data/information into human-readable form. Example- monitor, printer, speaker, projector etc.

Control Unit: 

The control unit handles the various components of the computer; it reads and interprets (decodes) the instructions for the program, transforming them into control signals that activate other computer parts.

Arithmetic Logic Unit: 

It is capable of performing arithmetical and logical functions. The set of arithmetic operations supported by a specific ALU may be restricted to addition and subtraction or may include functions of multiplication, division, trigonometries such as sine, cosine, etc., and square roots.

Central Processing Unit: 

The ALU, control unit and registers and together called the CPU. It is sometimes called the computer's brain, and its job is to perform commands. We send instructions to the CPU whenever we press a key, click the mouse, or start an application.

Software refers to computer parts, such as programs, data, protocols, etc., that do not have a material form. In contrast to the physical hardware from which the system is built, the software is that portion of a computer system consisting of encoded information or computer instructions.

It is sometimes called "firmware" when the software is stored in hardware that can not be easily modified, such as with a BIOS ROM on an IBM PC compatible computer.

Computer hardware and software require each other, and neither of them can be realistically used on their own. There are four main components of a general-purpose computer: the arithmetic logic unit (ALU), the control unit, the memory, and the I/O (collectively called input and output) devices.

Uses of Computer

Computers are used in various fields, such as homes, businesses, government offices, research organizations, educational institutions, medicine, entertainment, etc. because of their features and powerful functions. They have taken sectors and companies to a whole new level.

Science- 

Computers are best suited for the collection, analysis, categorization, and storage of data in science, research and engineering. They also help scientists to exchange data both internally and internationally with each other.

Government-  

Computers in the government sector are used to perform various functions and improve their services. In most cases, data processing tasks, the maintenance of citizens' databases, and the promotion of a paperless environment are the primary purposes of using computers. In addition to this, computers play a key role in the country's defence system.

Health and Medicine- 

They are used to preserve information, records, live patient monitoring, X-rays, and more from patients. Computers assist in setting up laboratory tools, monitoring heart rate and blood pressure, etc. Besides, computers allow physicians to easily exchange patient data with other medical specialists.

Education- 

They help people get different educational materials (such as images, videos, e-books, etc.) in one place. Also, computers are best suited for online classes, online tutoring, online exams, and task and project creation. Also, they can be used to maintain and track student performance and other data.

Banking- 

Most countries use online banking systems so that customers can access their data directly. People can verify the balance of their account, transfer cash, and pay online bills, including credit cards. Besides, banks use computers to execute transactions and store client information, transaction records, etc.

Short Computer Essay in English

A computer's a programmable device that accepts raw data(input) and processes it as output with a group of instructions (a program) to supply the result. It renders output after performing mathematical and logical operations and can save the output for future use. The word "computer" derives from the word "computare" in Latin, which means calculating.

Types of Computer

Computers are of different types based on different criteria. Based on their size, computers are of five types:

Micro Computers- 

It is a single-user computer that has less capacity for speed and storage than the other types. For a CPU, it uses a microprocessor. Laptops, desktop computers, personal digital assistants (PDAs), tablets, and smartphones are common examples of microcomputers. Microcomputers are generally designed and built for general use, such as browsing, information search, the internet, MS Office, social media, etc.

Mini Computers- 

Minicomputers are also referred to as "Midrange Computers." They are multi-user computers designed to simultaneously support multiple users. Therefore, they are generally used by small companies and firms. 

Mainframe Computers- 

It is also a multi-user computer that large companies and government organizations use to run their business operations as large amounts of data can be stored and processed. Banks, universities, and insurance companies, for example, use mainframe computers to store data from their customers, students, and policyholders.

Super Computer- 

Among all types of computers, supercomputers are the fastest and most costly computers. They have an enormous capacity for storage and computing speeds and can therefore perform millions of instructions per second.

Workstations-  

It is a single-user computer with a comparatively more powerful microprocessor and a high-quality monitor compared to a mini-computer.

Benefits of Computers:

It increases productivity.

It helps in connecting to the internet.

It helps in organizing data and information.

It allows storing large amounts of data.

Fun Facts About Computers

The first electric computer that was invented weighed around 27 tons or even more than that and took up to 1800 square feet.

There are about 5000 new viruses that are released every month.

The original name of Windows was Interface Manager.

It is surely known that the life of humans would not have been so easy if computers were not a part of human life. This is also supported by a lot of pieces of evidence where we can even see in daily life how the computer is not just present in an organization but is also available right in the pockets of everyone. Thus, the computer has surely made it easy while also spoiling a lot of people's lives.

FAQs on Essay on Computer

1. What are the disadvantages of computers?

While the computer has surely made life easier, it also has a lot of disadvantages. The disadvantages of the computers can be provided as follows:

People spend too much time sitting and doing nothing but watching the content on computers.

People staring at computers for a long time also tend to strain their eyes, and as a result, they need spectacles to understand what is being written in front of them.

Attention span is decreasing with an increase in the use of computers. 

With computers being AI-powered, it is now easier for people to do all the tasks on a computer and not work on it themselves. This has made a lot of people lazy.

2. What is the process of working on a computer?

A computer is an electronic machine and it needs information to be added in as raw data to function well. It has a flow that determines the accessing of data. The following steps take place before the results are obtained:

Information is taken in by the computer in the form of raw data. This process is also called the input.

Then the information that is not needed will be stored while the information that is needed is passed onto the next step. The storing of data is called memory.

Then the information that is required is crushed or it is split and this process is called processing.

The last step is where the results are obtained. This process is called getting the output.

computer

A computer is a machine that can store and process information . Most computers rely on a binary system , which uses two variables, 0 and 1, to complete tasks such as storing data, calculating algorithms, and displaying information. Computers come in many different shapes and sizes, from handheld smartphones to supercomputers weighing more than 300 tons.

Many people throughout history are credited with developing early prototypes that led to the modern computer. During World War II, physicist John Mauchly , engineer J. Presper Eckert, Jr. , and their colleagues at the University of Pennsylvania designed the first programmable general-purpose electronic digital computer, the Electronic Numerical Integrator and Computer (ENIAC).

What is the most powerful computer in the world?

As of November 2021 the most powerful computer in the world is the Japanese supercomputer Fugaku, developed by RIKEN and Fujitsu . It has been used to model COVID-19 simulations.

How do programming languages work?

Popular modern programming languages , such as JavaScript and Python, work through multiple forms of programming paradigms. Functional programming, which uses mathematical functions to give outputs based on data input, is one of the more common ways code is used to provide instructions for a computer.

The most powerful computers can perform extremely complex tasks, such as simulating nuclear weapon experiments and predicting the development of climate change . The development of quantum computers , machines that can handle a large number of calculations through quantum parallelism (derived from superposition ), would be able to do even more-complex tasks.

A computer’s ability to gain consciousness is a widely debated topic. Some argue that consciousness depends on self-awareness and the ability to think , which means that computers are conscious because they recognize their environment and can process data. Others believe that human consciousness can never be replicated by physical processes. Read one researcher’s perspective.

Computer artificial intelligence's impact on society is widely debated. Many argue that AI improves the quality of everyday life by doing routine and even complicated tasks better than humans can, making life simpler, safer, and more efficient. Others argue AI poses dangerous privacy risks, exacerbates racism by standardizing people, and costs workers their jobs leading to greater unemployment. For more on the debate over artificial intelligence, visit ProCon.org .

computer , device for processing, storing, and displaying information.

Computer once meant a person who did computations, but now the term almost universally refers to automated electronic machinery . The first section of this article focuses on modern digital electronic computers and their design, constituent parts, and applications. The second section covers the history of computing. For details on computer architecture , software , and theory, see computer science .

Computing basics

The first computers were used primarily for numerical calculations. However, as any information can be numerically encoded, people soon realized that computers are capable of general-purpose information processing . Their capacity to handle large amounts of data has extended the range and accuracy of weather forecasting . Their speed has allowed them to make decisions about routing telephone connections through a network and to control mechanical systems such as automobiles, nuclear reactors, and robotic surgical tools. They are also cheap enough to be embedded in everyday appliances and to make clothes dryers and rice cookers “smart.” Computers have allowed us to pose and answer questions that were difficult to pursue in the past. These questions might be about DNA sequences in genes, patterns of activity in a consumer market, or all the uses of a word in texts that have been stored in a database . Increasingly, computers can also learn and adapt as they operate by using processes such as machine learning .

Computers also have limitations, some of which are theoretical. For example, there are undecidable propositions whose truth cannot be determined within a given set of rules, such as the logical structure of a computer. Because no universal algorithmic method can exist to identify such propositions, a computer asked to obtain the truth of such a proposition will (unless forcibly interrupted) continue indefinitely—a condition known as the “ halting problem .” ( See Turing machine .) Other limitations reflect current technology . For example, although computers have progressed greatly in terms of processing data and using artificial intelligence algorithms , they are limited by their incapacity to think in a more holistic fashion. Computers may imitate humans—quite effectively, even—but imitation may not replace the human element in social interaction. Ethical concerns also limit computers, because computers rely on data, rather than a moral compass or human conscience , to make decisions.

Analog computers use continuous physical magnitudes to represent quantitative information. At first they represented quantities with mechanical components ( see differential analyzer and integrator ), but after World War II voltages were used; by the 1960s digital computers had largely replaced them. Nonetheless, analog computers, and some hybrid digital-analog systems, continued in use through the 1960s in tasks such as aircraft and spaceflight simulation.

One advantage of analog computation is that it may be relatively simple to design and build an analog computer to solve a single problem. Another advantage is that analog computers can frequently represent and solve a problem in “real time”; that is, the computation proceeds at the same rate as the system being modeled by it. Their main disadvantages are that analog representations are limited in precision—typically a few decimal places but fewer in complex mechanisms—and general-purpose devices are expensive and not easily programmed.

Digital computers

In contrast to analog computers, digital computers represent information in discrete form, generally as sequences of 0s and 1s ( binary digits, or bits). The modern era of digital computers began in the late 1930s and early 1940s in the United States , Britain, and Germany . The first devices used switches operated by electromagnets (relays). Their programs were stored on punched paper tape or cards, and they had limited internal data storage. For historical developments, see the section Invention of the modern computer .

During the 1950s and ’60s, Unisys (maker of the UNIVAC computer), International Business Machines Corporation (IBM), and other companies made large, expensive computers of increasing power . They were used by major corporations and government research laboratories, typically as the sole computer in the organization. In 1959 the IBM 1401 computer rented for $8,000 per month (early IBM machines were almost always leased rather than sold), and in 1964 the largest IBM S/360 computer cost several million dollars.

These computers came to be called mainframes, though the term did not become common until smaller computers were built. Mainframe computers were characterized by having (for their time) large storage capabilities, fast components, and powerful computational abilities. They were highly reliable, and, because they frequently served vital needs in an organization, they were sometimes designed with redundant components that let them survive partial failures. Because they were complex systems, they were operated by a staff of systems programmers, who alone had access to the computer. Other users submitted “batch jobs” to be run one at a time on the mainframe.

Such systems remain important today, though they are no longer the sole, or even primary, central computing resource of an organization, which will typically have hundreds or thousands of personal computers (PCs). Mainframes now provide high-capacity data storage for Internet servers, or, through time-sharing techniques, they allow hundreds or thousands of users to run programs simultaneously. Because of their current roles, these computers are now called servers rather than mainframes.

Six papers by CSE researchers at STOC 2024

A stylized illustration of overlapping graph/network nodes in pastel colors against a dark blue background

Six papers by researchers in CSE have been accepted for presentation at the 2024 ACM Symposium on Theory of Computing (STOC), taking place in Vancouver, Canada, from June 24-28. Held annually since 1969, STOC is the top international conference in theoretical computer science, bringing together the top minds in the field to share their latest findings and ideas.

CSE authors contributed to six out of 198 total papers accepted by the conference, with their work spanning a range of topics related to computing theory, from approximation algorithms for vertex cuts and dense linear systems to multi-commodity flow emulators and correlation clustering. 

The following papers are being presented at the conference, with the names of authors affiliated with CSE in bold:

“ Approximating Small Sparse Cuts ” Aditya Anand , Euiwoong Lee , Jason Li, Thatchaphol Saranurak

Abstract: We study polynomial-time approximation algorithms for edge and vertex Sparsest Cut and Small Set Expansion in terms of k, the number of edges or vertices cut in the optimal solution. Our main results are O (polylog  k )-approximation algorithms for various versions in this setting. Our techniques involve an extension of the notion of sample sets (Feige and Mahdian STOC ’06), originally developed for small balanced cuts, to sparse cuts in general. We then show how to combine this notion of sample sets with two algorithms, one based on an existing framework of LP rounding and another new algorithm based on the cut-matching game, to get such approximation algorithms. Our cut-matching game algorithm can be viewed as a local version of the cut-matching game by Khandekar, Khot, Orecchia and Vishnoi and certifies an expansion of every vertex set of size s in O (log s ) rounds. These techniques may be of independent interest. As corollaries of our results, we also obtain an O (log opt ) approximation for min-max graph partitioning, where opt is the min-max value of the optimal cut, and improve the bound on the size of multicut mimicking networks computable in polynomial time.

“ Solving Dense Linear Systems Faster than via Preconditioning ” Michał Dereziński , Jiaming Yang

Abstract: We give a stochastic optimization algorithm that solves a dense n × n real-valued linear system Ax = b , returning x such that || A x− b ||≤ є|| b || in time: Õ(( n 2 + nk ω−1 )log1/є), where k is the number of singular values of A larger than O (1) times its smallest positive singular value, ω < 2.372 is the matrix multiplication exponent, and Õ hides a poly-logarithmic in n factor. When k = O ( n 1−θ ) (namely, A has a flat-tailed spectrum, e.g., due to noisy data or regularization), this improves on both the cost of solving the system directly, as well as on the cost of preconditioning an iterative method such as conjugate gradient. In particular, our algorithm has an Õ( n 2 ) runtime when k = O ( n 0.729 ). We further adapt this result to sparse positive semidefinite matrices and least squares regression. Our main algorithm can be viewed as a randomized block coordinate descent method, where the key challenge is simultaneously ensuring good convergence and fast per-iteration time. In our analysis, we use theory of majorization for elementary symmetric polynomials to establish a sharp convergence guarantee when coordinate blocks are sampled using a determinantal point process. We then use a Markov chain coupling argument to show that similar convergence can be attained with a cheaper sampling scheme, and accelerate the block coordinate descent update via matrix sketching.

“ Low-Step Multi-Commodity Flow Emulators ” Bernhard Haeupler, D Ellis Hershkowitz, Jason Li, Antti Röyskö, Thatchaphol Saranurak  

Abstract: We introduce the concept of low-step multi-commodity flow emulators for any undirected, capacitated graph. At a high level, these emulators contain approximate multi-commodity flows whose paths contain a small number of edges, shattering the infamous flow decomposition barrier for multi-commodity flow.

We prove the existence of low-step multi-commodity flow emulators and develop efficient algorithms to compute them. We then apply them to solve constant-approximate k -commodity flow in O (( m + k ) 1+є ) time. To bypass the O ( mk ) flow decomposition barrier, we represent our output multi-commodity flow implicitly ; prior to our work, even the existence of implicit constant-approximate multi-commodity flows of size o ( mk ) was unknown.

Our results generalize to the minimum cost setting, where each edge has an associated cost and the multi-commodity flow must satisfy a cost budget. Our algorithms are also parallel.

“ Optimal Embedding Dimension for Sparse Subspace Embeddings ” Shabarish Chenakkod, Michał Dereziński , Xiaoyu Dong, Mark Rudelson

Abstract: A random m × n matrix S is an oblivious subspace embedding (OSE) with parameters є>0, δ∈(0,1/3) and d ≤ m ≤ n , if for any d -dimensional subspace W ⊆ R n , P ( ∀ x∈ W (1+є) −1 || x ||≤ || Sx ||≤ (1+є)|| x || )≥ 1−δ. It is known that the embedding dimension of an OSE must satisfy m ≥ d , and for any θ > 0, a Gaussian embedding matrix with m ≥ (1+θ) d is an OSE with є = O θ (1). However, such optimal embedding dimension is not known for other embeddings. Of particular interest are sparse OSEs, having s ≪ m non-zeros per column (Clarkson and Woodruff, STOC 2013), with applications to problems such as least squares regression and low-rank approximation.

We show that, given any θ > 0, an m × n random matrix S with m ≥ (1+θ) d consisting of randomly sparsified ±1/√ s entries and having s = O (log 4 ( d )) non-zeros per column, is an oblivious subspace embedding with є = O θ (1). Our result addresses the main open question posed by Nelson and Nguyen (FOCS 2013), who conjectured that sparse OSEs can achieve m = O ( d ) embedding dimension, and it improves on m = O ( d log( d )) shown by Cohen (SODA 2016). We use this to construct the first oblivious subspace embedding with O ( d ) embedding dimension that can be applied faster than current matrix multiplication time, and to obtain an optimal single-pass algorithm for least squares regression.

We further extend our results to Leverage Score Sparsification (LESS), which is a recently introduced non-oblivious embedding technique. We use LESS to construct the first subspace embedding with low distortion є= o (1) and optimal embedding dimension m = O ( d /є 2 ) that can be applied in current matrix multiplication time, addressing a question posed by Cherapanamjeri, Silwal, Woodruff and Zhou (SODA 2023).

“ Understanding the Cluster Linear Program for Correlation Clustering ” Nairen Cao, Vincent Cohen-Addad, Euiwoong Lee , Shi Li, Alantha Newman, Lukas Vogl 

Abstract: In the classic Correlation Clustering problem introduced by Bansal, Blum, and Chawla ‍(FOCS 2002), the input is a complete graph where edges are labeled either + or −, and the goal is to find a partition of the vertices that minimizes the sum of the +edges across parts plus the sum of the -edges within parts. In recent years, Chawla, Makarychev, Schramm and Yaroslavtsev ‍(STOC 2015) gave a 2.06-approximation by providing a near-optimal rounding of the standard LP, and Cohen-Addad, Lee, Li, and Newman ‍(FOCS 2022, 2023) finally bypassed the integrality gap of 2 for this LP giving a 1.73-approximation for the problem. While introducing new ideas for Correlation Clustering, their algorithm is more complicated than typical approximation algorithms in the following two aspects: (1) It is based on two different relaxations with separate rounding algorithms connected by the round-or-cut procedure. (2) Each of the rounding algorithms has to separately handle seemingly inevitable correlated rounding errors , coming from correlated rounding of Sherali-Adams and other strong LP relaxations. In order to create a simple and unified framework for Correlation Clustering similar to those for typical approximate optimization tasks, we propose the cluster LP as a strong linear program that might tightly capture the approximability of Correlation Clustering. It unifies all the previous relaxations for the problem. It is exponential-sized, but we show that it can be (1+є)-approximately solved in polynomial time for any є > 0, providing the framework for designing rounding algorithms without worrying about correlated rounding errors; these errors are handled uniformly in solving the relaxation. We demonstrate the power of the cluster LP by presenting a simple rounding algorithm, and providing two analyses, one analytically proving a 1.49-approximation and the other solving a factor-revealing SDP to show a 1.437-approximation. Both proofs introduce principled methods by which to analyze the performance of the algorithm, resulting in a significantly improved approximation guarantee. Finally, we prove an integrality gap of 4/3 for the cluster LP, showing our 1.437-upper bound cannot be drastically improved. Our gap instance directly inspires an improved NP-hardness of approximation with a ratio 24/23 ≈ 1.042; no explicit hardness ratio was known before.

“ Connectivity Labeling and Routing with Multiple Vertex Failures ” Merav Parter, Asaf Petruschka, Seth Pettie

Abstract: We present succinct labeling schemes for answering connectivity queries in graphs subject to a specified number of vertex failures. An f -vertex/edge fault tolerant ( f -V/EFT) connectivity labeling is a scheme that produces succinct labels for the vertices (and possibly to the edges) of an n -vertex graph G , such that given only the labels of two vertices s , t and of at most f faulty vertices/edges F , one can infer if s and t are connected in G − F . The primary complexity measure is the maximum label length (in bits). The f -EFT setting is relatively well understood: [Dory and Parter, PODC 2021] gave a randomized scheme with succinct labels of O (log 3 n ) bits, which was subsequently derandomized by [Izumi et al., PODC 2023] with Õ( f 2 )-bit labels. As both noted, handling vertex faults is more challenging. The known bounds for the f -VFT setting are far away: [Parter and Petruschka, DISC 2022] gave Õ( n 1−1/2Θ( f ) )-bit labels, which is linear in n already for f =Ω(loglog n ). In this work we present an efficient f -VFT connectivity labeling scheme using poly ( f , log n ) bits. Specifically, we present a randomized scheme with O ( f 3 log 5 n )-bit labels, and a derandomized version with O ( f 7 log 13 n )-bit labels, compared to an Ω( f )-bit lower bound on the required label length. Our schemes are based on a new low-degree graph decomposition that improves on [Duan and Pettie, SODA 2017], and facilitates its distributed representation into labels. This is accompanied with specialized linear graph sketches that extend the techniques of the Dory and Parter to the vertex fault setting, which are derandomized by adapting the approach of Izumi et al. and combining it with hit-miss hash families of [Karthik and Parter, SODA 2021]. Finally, we show that our labels naturally yield routing schemes avoiding a given set of at most f vertex failures with table and header sizes of only poly ( f ,log n ) bits. This improves significantly over the linear size bounds implied by the EFT routing scheme of Dory and Parter.
