Of the six of us with CS degrees, I learned that two had never written a program of any kind and had never used a computer more than casually (writing papers, playing games, etc.). building my own computers from parts and installing ALL the software, Finding an absolute answer isn't feasible, but there are search algorithms that could give a pretty good "guesstimate". having to write hard programs (like my own virtual machine with a custom assembly language, or a Huffman compression implementation, etc. Roger S. Pressman made it scholarly before Steve McConnell made it fashionable. algorithms, what algorithm(s) do you Suppose one of your friends gets a job at some place X and, while there, a manager makes a few simple requests, such as these examples: Ex 1: We have a large fleet of delivery vehicles that visit different cities across several states. What theory should provide you with is the big picture and a sense of how basic concepts fit together. See: most mathematical theories. It is about Quantum supremacy and it is intended for a general audience of both computer science and physics. Existing theoretical knowledge on unintended consequences is not well integrated. A friend of mine is doing work on a language with some templates. The central open problem of complexity theory, P vs NP, is just a formalisation of another philosophically significant question: is it really harder to solve a problem than to check if an alleged solution of it is indeed correct? At the same time, it relied on important developments in theoretical computer science. Can you do it? The halting problem and automata/Turing Machine theory? What would justify those road like structures. A few weeks after I was hired, one of them asked me this question: There are 106 airports in Arkansas. If you don't have any of these abilities, you probably won't be able … How to efficiently read the theoretical computer science research papers? In fact, they have no idea why the system works at an "acceptable" level when checking 5 cities, yet becomes very slow at 10 cities, and just freezes when going up to only 40 cities. It means worked out on paper rather than the lab. Theoretical Computer Science Stack Exchange is a question and answer site for theoretical computer scientists and researchers in related fields. No exceptions. Yet another failure... your friend now feels "dumb" for not having been able to solve this "simple problem"... after all, the request itself made it sound simple. When ought rockoons to be used? There are several other very useful resources on additive combinatorics, which readers may wish to consult: The book “Additive Combinatorics” by Tao and Vu [67] gives a detailed description of many results in additive combinatorics and their applications, mainly in number theory. Thinking the theory is 'useless' your friends don't realize that they've just been given the Traveling Salesman Problem (TSP) and start designing this system without a second thought, only to discover their naive attempt to check all the possibilities, as originally requested, is so slow their system is unusable for any practical purposes. He was mystified, then confessed that he did not actually know what made a plane fly!?! I seriously thought he was quizzing me on my knowledge of the Traveling Salesman Problem and NP-Completeness. I'm currently starting on the university [computer science] and there we have lot of opportunities to begin with researching. I can relate my reasons as an undergraduate applying to TCS graduate programs this upcoming Winter (so little time left!). Tools from analysis are useful in the study of many problems in theoretical computer science. So there is clearly overlap between the two fields, but they are far from the same. Most importantly, after I have learned all that, I have learned that I don't know a damned thing. Was it really a coincidence that, for most of history, no one was able to build a flying machine (and a few even died testing theirs) until the Wright brothers understood certain theoretical concepts about flight and managed to put them into practice? When I came across Turing's paper in college I did not feel enlightened at all. turing machines), write code, which relies on computability theory (e.g. Computer Science (Classe LM-18)-enrolled from 2014/2015 academic year Learning objectives The course aims at introducing basics of computability and complexity theory, suitably presenting theoretical tools also useful to rigorously approach several other issues in computer science. It's a fact that someone who simply use a plane to travel doesn't need to understand the theory that even allowed planes to be built and fly in the first place... but when someone is expected to build said machines and make them work... can you really expect a good outcome from someone who doesn't understand even the principles of flight? Not every one is equal, and that is okay--I am not a better person because I can program effectively, but I am more useful IF that is what you need from me. "[…] this set is the most unique and possibly the most useful to the [theoretical computer science] … Theoretical Computer Science jobs. Good post :) I recently took a couple of math related classes (PDEs, Tensors, Cryptography, image processing, etc) and I'm sure it will pay off. Complexity is a good thing to know about. Page 1 of 166 jobs. I was asked for help a lot, did some tutoring, was asked to help with a research project, and was allowed to do independent study when no one else was. rely on color theory and models (e.g. Informatics finds its way into many different applications - stuff everyone from the DHD to, There's the challenge. Sooner or later, the right amount of pressure from the right angle will make it collapse in on itself. Handbook of Theoretical Computer Science. These include algorithms, logic, automata theory, … Computer Science theory is necessary for a deep understanding of algorithms, and that in turn helps with programming. Once it works in theory, I start coding and testing, checking off the states as i go. I think the easiest way to distinguish theory from application is to look at the field's definition of a computer. Menu . See Euler's work, some of that wasn't proved absolutely till recently, and can't be comprehended by more than a handful of people in the world. Theory is the underlying foundation on top of which other things are built. Now that we possess a class of mathematical objects describing computations, we can actually prove theorems about them, thus trying to uncover what can be computed, and how it can be computed; it immediately turned out that lots of perfectly legitimate functions cannot be computed at all, and that they can be classified according to a degree of uncomputability (some functions are just “more uncomputable” than others). Why is EAX being cleared before calling a function if I don't include the header? It would also be nice to know why understanding memory allocation, paging, etc, data structures, multi-tasking, etc, is important by giving concrete examples. Having built an interpreter for the templates, a computer scientist might notice that the majority of templating requests are duplicates, regenerating the same results over and over again. Theoretical computer science topics. Paul Erdos talked about the "Book" Theoretical Computer Science Cheat Sheet by Steven S. Seiden (pdf)-- commonly used formulas and other useful information for computer scientists. If so, it’s important to have a strong grounding in both mathematics and computer science. Thats important to appreciate. … In the present day, it deals heavily with quantum computers, which perform mathematical computations on the wavefunction of a particle. i spent some time to figure this out but if i had paid more attention to the "approximation of Double and Float" lesson i would have not wasted that time. Was there an organized violent campaign targeting whites ("white genocide") in South Africa? Alan Cobham and Jack Edmonds were quite successful in identifying a reasonable notion of “efficient computation”. Machine learning clearly gives people the opportunity to do both theory and programming, but I am sure it's not the only subfield of CS for which it's true. Conclusions are drawn and it is shown that these may be useful for practitioners. My favourite example is the time hierarchy theorem: if we are given more time to compute, we can solve harder problems. Can I give "my colleagues weren't motivated" as a reason for leaving a company? however, of thirteen of us, 6 had form of computer-related degree; other 7 had degrees ranging aeronautics chemistry/biology psychology. Since one of my classmates had a degree in aeronautics, I asked him about it.
