Same here, I'll get it next year I think. Don't even know what that shit is about.

It's a bone thrown to the actual research professors...along with pointless undergraduate linear algebra. Combinatorics, graph theory and linear algebra are immensely important but the class will probably sucks won't help GIT A JERB.

You're doing Computer Science, anon. Obviously you need a high level of mathematics knowledge from principles of logic and predicate calculus all the way up, else how are you going to derive prove algorithmic complexities expressed in big-O notation? Without learning about Abelian rings in the context of modulo arithmetic, how would you learn ladder multiplication and exponentiation algorithms so you know how computers actually do arithmetic? Have you ever even done any functional programming, or understand any formal correctness proof methods?

You have no idea what I'm talking about, do you? You just wanted to code shit PHP, don't you?

Oh boy, did you ever pick the wrong course. CS is applied mathematics. Abort while you can. You may be early enough to commute to a course you'll find easier.

You wanted games programming, that's the meme shit degree this year. (Joke's on you, you need a high level of vector maths knowledge to hack it there, too.)

>>56224545
Even if you want to be a game developer these days you better be good at maths.

Here comes the hoards of faggots that think they're superior for reading SICP once and skimming through Calc I. It's common knowledge that discrete mathematics is one of the shittier classes just because of the lack of good material on it.

Anyone who has studied applied math or CS would feel sympathy for OP as he is too chained to that shitty book in the pic.

>You wanted games programming, that's the meme shit degree this year. (Joke's on you, you need a high level of vector maths knowledge to hack it there, too.)
No you don't, you need linear algebra which is taught in high school, but you wouldn't know.
I mean I feel sorry for you, you're probably dumber than OP.

>>56224487
>Why the fuck do I need to learn this gay fucking shit in my CS course

um, algorithim analysis?

Computer science is maths.

If you want to be a code monkey you don't need a degree and you don't need to study, just go get a code monkey job.

If you aren't interested in esoteric knowledge then you shouldn't be at a university. Especially if you just don't want to learn.

You have to find materials for it on Backpage.

>>56224657
Discrete math was one of my favorite courses, and I actually kept the book afterwards. And it's not worthless, I've applied some of the principles in my job. If you can't understand it or how you would apply it, then you need to start over and focus.

>>56225007
because the elements/data/space/topology you handle in these courses are discontinuous, and those are called discrete.

>>56224487
Stop fucking complaining. Look at that book and look hard. When I took the class, I took it with the indisputably worst teacher at my uni and the only resource we had was the 200 page book HE FUCKING WROTE. The book was literally just the transcript of his lecture, so he read from it word for word, then he would assign problems that were nonstandard so we couldn't look up an explanation online.

If we went in for help, he would complain that we should just read the book, then repeat what he had said in class without answering any questions. Ultimately a group of four of us had to guess and check tweaking tiny things until the program worked, and we would have no idea how or why.

If you have an actual book, you're already one step up.

There was part of discrete math classes is that they are teaching people that did not enjoy math too much before some dumb rules and exercises.

I mean.

If you are at some top uni you problem know basic before or atleast you are conscious how important is discrete match in cs.

They should teach discrete match with examples of real wold usage.

Yo uare solvin exercise and you can learn how to use it in real cs problems.

Hahhahahaha all these poo in loo programmers who cant do some basic discrete maths.

>>56225750
Its funny word on imageboard that 90% of people do not code at all, 2% is proffesionall C/Lisp fizz buzzers and 8% are webdevs.

Programming is job as any other job. Its not fucking art or duty.

Most of adult people have kids and family that they are responsible for.

They have to make money.

We live in era where nobody give a fuck about code quality, documentation or unit test.
Client is interesed in final product.
Producer want to cut costs.


We need this people, because market is big as fuck and in most cases companies want some simple programs not high level advence shit.


Every person will hit limit at some point. Even if they learn all math in cs, what would it change? they would do the same job as now.


For somebody his limit is web dev, for other algos.

Learning math is not about being able to solve shit but about understading certain concepts to the point where you can find on your own application of this math in your project and if require you can modify math part of the code to fit your problem well.


We are not equal. Everybody hit his peak and majority of human are lazy and dumb as fuck.

>>56225936
Why don't you learn some English before defending idiots?

It's called discrete mathematics because the fucking nerds who study this shit should be as discrete as possible so the rest of us can get on with important things.

I agree, everyone should just proceed to be a miserable sack of shit, with no will or desire for major improvement

OP is a retard. If anything, Calculus is the unecessary class with discrete mathematics a prerequisite to take and understand data structures. Hell even probability/statistics appears far more often. Though anyone who hated math is a pleb, it is far more enjoyable than the software engineering and business parts of CS.

>>56226522
Read nigga I said the SE and business parts of CS which involve little programming. If you ever took high level math classes, even at least numerical analysis and advanced linear algebra (both being able to heavily incorporate programming) you would learn the joy that is math combined with programming. Nothing better than analyzing a math function theoretically and implementing with your wizarding skills and seeing it work.

>>56225936
Hey man, I'm here for you if you want to talk

>>56225007
Discrete means the opposite of continuous, basically anything you can count with integers. For example, the real number line is continuous, while the integers are discrete.

>>56226020
You say that, but I know for a fact that you'll never amount to anything.

He is right, goys. Just learn your Java and C# and ignore graph theory and combinatorics.

Im coming from the opposite direction, i finished a discrete math class last semester. We covered logic, trees and graphs, and did a little bit on encryption.

Can someone tell me what i should learn next? Does polish/reverse polish notation come up much? Is the logic mainly used for logic gates? I have this knowledge but no reference of how important the discrete math ideas are.

>>56225967

are you even working? do you have kids?
are you spending summer shitposting in rice my deskopt and meme keyboard general?


If any of you work in some high level shit like coding soft for airspace/military missles or other places where math is crucial okay.


but in modern software engineering there is barely place for your meme math innovation.
99% is just coding some shit, the biggest math challenge will be what kind of interpolation will fit the best or what one sorting algo is more efficient than other.

Its great that you want improve yourself, but you have this dream vision of the world.

Again
Barely anybody on /g/ code.

To be honest, it's because CS is such a very young discipline.

We're already seeing the shift between the actual "computer science" and, for lack of a better word, "computer engineering" (though not actual computer engineering, which is a subset of electrical engineering)... "Applied computer science" would be a better term, but that's like calling engineering "applied physics" - it's true, but not the whole story.

No, knowing semi-advanced mathematics, formal computation, or how to analyse algorithms will not make you a better codemonkey - 99% of your career you will use libraries or algorithms designed by others, the other 1% of the time it won't matter - unless were writing very specialized programs for very specialized circumstances.

>>56226948
What is the point of learning new things if you are never able to use it and your time on earth is limited?

8h job, 2h commute, dinner, help kids with school, you will have barely free time and after 8h of dazing into some shitty 20yo project wihtout any kind of sane documentation and full of """fast fixes""", watching bright screen again at home will be the last thing.

>>56229224
that sounds like a lot less discrete math and a lot more algorithms and data structures. save for the logic. did u enjoy that class?

>>56229300
>2h commute
have you considering moving or apply to work elsewhere?

>>56224487

I fell in love with this book pretty quick, but I could imagine some people hating it. The writer is playing chess with the reader, not for everyone.

No. Even the most advanced high schools rarely go past basic calculus. Linear algebra, while not that difficult, is at a slightly higher level than basic calculus. I've never heard of LA being taught at the high school level.

>>56229733
>linear algebra slightly higher level than basic calculus

Really? I would guess calc I is just slightly higher level than linear algebra. Linear algebra to calculus seems like a more sensible order as linear algebra is easier.

>>56229845
how deep into linear algebra are we talking here? the basics aren't too bad, but once you get into eigenvalues and shit, it starts to get a little difficult.

Algorithms are pretty important. Shortest path, max flow/ min cut, Euler cycles, hypercubes, set theory, even basic logic, all have massive application.

You really can't write a useful program without some basic grasp of these types of concepts.

And even if you manage to without the kind of advanced algorithms learned in discrete, it will be optimized like shit and someone else who does know this shit will design a better alternative.

Its pretty fucking true what this guy said, to a degree anyway. Basically, your boss/company wants to produce a product that brings in the money, and you want the money to survive. This really dumb fundamental principle, for better or for worse, governs most things.
If there is something you love about programming, even if it is niche, I suggest you learn it first for yourself, and later on you may find some of it carries over into production, but this really isn't guaranteed.

>>56229904
Linear algebra snuck up on me hard. I breezed through the first few chapters and put it on the lowest priority in my study routine. Then the second exam came and demolished me.

For any nontrivial algorithms, it's an important thing to know.

I just worked on an NLP project where I had to use NFA's to model sentences because regular graph theory wasn't really the right tool for the job.
NLP, AI, compiler design, all these fields use these concepts a lot.

wow I hardly ever post but finished with 2 years of CS at a state university. Found Discrete maths 1-2 to be difficult as fuck but extremely enlightening and rewarding.

Solving recurrence relations (while difficult when it generates complex numbers) doesn't interest you in the implication that the same techniques can be used to optimize recurrence algorithms?

Understanding the Inclusion / Exclusion principle doesn't help you think about how complicated probability problems can be solved?

You weren't mind fucked in any of that part about countable vs uncountable sets and the idea of Aleph Numbers?

Graph theory isn't important? Doesn't seeing how hard it is to find graph isomorphic by hand show you how difficult it is for computers to do it either?

Even if the actual pen to paper math is difficult (and it is for a lot of people!) the concepts alone make it more than worth it. Why are you complaining?

This is because CS and programming are not mutually inclusive, and the former hires much, much less than the latter.

Basically this.. If you don't have a solid understanding of mathematics and how to properly analyze systems you're going to lose ground to people willing to work much more cheaply than you. What they teach in most CS programs these days gets you "manual laborer" status in the tech world.

If you can't hack it in a basic CS program you might be better off saving your money and going straight to Starbucks.

It's funny when physicists think they know jack shit about mathematics when they wonder why their Hamiltonian isn't second quantizable and why their S-matrix elements aren't asymptotically summable.

The typical intro to quantum course is taught from Schrodinger's formalism of wavefunctions, which obfuscates the algebraic structure underlying quantum theories; the replacement of the Poisson bracket with the commutator wouldn't be justified until much later in the typical student's academic career. And when their second quantum course is taught from the Heisenberg's perspective they start freaking out: "hurr where did my C^inf go? why is there group theory in my quantum mechanics?" You have no fucking idea how many engineers and bottom-of-the-barrel physics majors complain about the tiny bit of abstract algebra they need for a spin-oriented approach to QM. Fucking shit I'm so fucking sick of it.

Pick one lmao. All you need to know are calc 1 and how to count.
