    Yes. K_{3,3} can be embedded on a torus.

    Theory cs could care less about coding abilities. It's never a bad thing to know how to code, but I can go though the entire PhD program without coding a single line of code. (Well…

    It's hard for someone in anything remote to math/science without coding anything in their entire undergraduate life. It's like you say no one can be admitted to a PhD program in US…

    1. There is no proof that pi is a normal number. 2. The index of the position takes up space.

    mathematician make errors. I want something that can be checked formally.

    This is why I think it be important to have a language designed to express algorithms and can be verified of correctness to a certain point.

    I haven't done any statistical surveys, in my undergrad years, I find math students are much smarter than the cs majors.

    Why do you care about the high demand? We can put that aside for now--if you are a competent coder, you are in high demand... If you want to have more math, then some subfield in C…

    It could mean "2/3 of the men who took the survey admit to watching porn" for w/e survey they had in mind...

    How about "Math beyond arithmetic is not important at all for the vast majority of adults today."

    This is a common technique of switching between two algorithms. iirc, I never saw this as an material in undergrad algorithms course. I wrote on another problem that uses this tech…

    Google Analytics has a filter system that allow one to use regular expressions of length at most 255. Sometimes, people have long list of strings that have total length more than 2…

    Since I'm a CS theory person, I can offer some theoretical improvements on the running time and make the problem even more general... Instead of minimize the linear difference of p…

    I thought you would want the most negative cycle, which would be NP-hard to find.

    Let's put some algebra/order into this... Bellman-Ford works for any totally ordered group (G,+), such that a+b What logarithm does is just a order preserving homomorphism from (R,…

    Good article, but it only demonstrate his ignorance on existing cache-oblivious data structures...
