if you've taken a course on discrete mathematics, all those books shouldn't take much longer than a month each to work through

[Anonymous No.11787664]

>>11787645
Working through CLRS in a month would be a very impressive feat even if you were already familiar with it. That's like 40 pages a day of reading plus 40 problems a day

[Anonymous No.11787684]

>>11787664
if you cut the section at the end of the crap u will never use/need then its around 700 pages which is 23 pages a day for a month, if you have a strong background with discrete math then i don't think it's too difficult if you spend 2-3 hours a day on it

Lmao half of concrete math is continous (literally CON from continuous and CRETE from discrete)
The majority of the latter chapters of Knuth's book hail from analysis and generating functions, and are definitely nontrivial, especially if all you've done is discrete mathematics.
CLRS isn't super *hard* but it's comprehensive and full of material - more than a month's worth for sure, if you want to do everything.
Theory of Computation by Sipser is legitimately very easy though, and can be done in about a month up to complexity. That's the only "trivial" one on the list.

if I read Discrete Mathematics by Rosen, will I be able to understand CLRS. I've tried CLRS and its way too fucking hard for my smooth brain.

CLRS is a collection of algorithms and techniques for the early undergrad canon. You would be better serviced doing optimization and algebra books (especially given the ridiculously important role of ring theory and linear algebra in algorithms), but CLRS remains a good reference book to start with nonetheless.
>blue man meme is right
Eh maybe for undergrads in CS, but when you hit grad all of that falls to the wayside and all people care about is your research.

linear algebra i understand, but how is ring theory important in algorithms? are you talking about computer algebra (factorisation of polynomials and so on)? that's not exactly what one typically understands by "aglorithms", it's more specialised than that

>but how is ring theory important in algorithms?
almost all of modern cryptography research, images and signals (segmentation), cyclic linear codes, etc. is predicated on ring theory. More generally, semirings show up broadly in TCS, and algebraic geometry shows up in geometric complexity and communication complexity.
If you name some field of mathematics, chances are it's relevant in TCS.

so this is what you meant, you could've just said "cryptography", you fucking faggot, these topics are typically broached in a separate subject, not as general "algorithms" (the kind of thing CLRS covers)

didn’t have a textbook for the class, but a combinatorics class I took just to fill in my schedule was way harder than I expected

[Anonymous No.11790353]

>>11790325
combinatorics usually takes people by surprise.
almost every "pure" analyst I've met (ie, the people who like real and complex analysis and nothing else) either shits on combinatorics because they've heard the memes but never taken the course, or they were completely assblasted by the course. The only part they remotely liked was the intersection, which was generating functions...and even then they were more wary after the class.
So if you see analysisfags shitting on combinatorics, know it's almost always in cope or ignorance.
