Computer science majors have to learn a different kind of math compared to MOST other majors (with the exception of math majors, plus computer and software engineers). This kind of math is important especially for those looking to go into research in fields like computer science, A.I., or even pure mathematics.

High school students who want to go to STEM majors in college should watch your videos. You cover subjects in-depth with practical examples. This is what is lacking in the majority of career/major prep videos on KZbin. The other channels would say "you need to know math" but are not really specific like you.

[@47Mortuus]

As a math student and passionate programmer... Math isn't as hard. You get taught - or you at the very least read - derivations and explanations and at some point you just UNDERSTAND the thought behind some proof and almost mindlessly apply this once understood principle in many places. You can get very, VERY far just by understanding, even if you regularly have to read a single sentence for hours in order to get it. Writing your own algorithms applied to 100% unique problems, though, is an almost entirely different beast(no matter how simple they might seem!). You start from scratch and never get any hints. You end up testing/trying to understand even the simplest steps one by one, thinking of possible edge cases etc.

[@blueberry44.]

[@justtoleavecomments3755]

Compsci grad student checking in to say the math you need for computer science highly depends on which part of computer science you go into. What he covered in this video, graph theory and some combinatorics is pretty ubiquitous, but linear algebra and probability is arguably just as much so. If you want to go into computer graphics youre gonna need multivar calc and linalg minimum, animation will need you to pickup differential equations too, and geometric modeling requires differential geometry. Want to go into computer networking? Linalg, statistics, and coding theory. Machine Learning/AI need so much math, if you're interested in those youre honestly better off getting a degree in math. If you're more hardware oriented, formal verification, microarchitectures and the such will need mathematical proof, differential equations, and some statistics. For building low level software, kernels, and compilers etc, lots of the stuff mentioned in this video - graphs/trees are all over the place, but you'll need to know some probability here too. TL;DR Linear Algebra, Probability, Combinatorics, Multivariable Calculus and Differential Equations will cover everything you could need for undergrad (in addition to the above).

[@mechinizer6911]

Hey, I wasn't the only person who required physics to earn a CS degree. I think that must be a major difference between a quality CS course and a bad one. The bad thing about people who take bad courses at schools is that they cannot grasp why physics would be needed in CS. It just blows my mind how many people do not realize the amount of things a programmer does with physics. There are literally people on here arguing against physics, simply because their course didn't require it. Not knowing physics might work if all I did was create BSTs all day. LOLZ! Let's see, without physics we don't have video games, any simulators period, conversions in temperatures, or equations for motion. We couldn't handle coupled systems, momentum and collision simulations, or simulate friction.

[@Darticus42]

Anthony Reese from a theoretical stand point, yeah there's more than discrete math and number theory. you need that fundamental logical reasoning used in discrete math / number theory regardless of what you do, which is why any half-decent CS curriculum includes those two. However, There are many other fields in CS that use other math, but are by no means necessary to succeed in every programming career. Linear Algebra & Vectors for AI/algorithm design/graphical transformation/crypto, Stats for data science, physics in modeling/simulations, and so on. I agree it's better to take most of those courses due to their wide ranging applications, but ultimately there's plenty of programming jobs you can take without touching any more than intro high school math. It's more to expand your horizons and understand the theory and design instead of just using it. For example, I haven't learned much college physics (only through AP); could I use my trig and algebra knowledge to implement basic simulations of gravity, momentum, current, by applying the equations I learned? Sure. But could I be the person that takes the constraints of the problem and derives an applicable equation? Probably not without a lot of research and self-teaching

If you are interested in programming but we’re scared off by the first problem: I’ve been programming for over a decade and haven’t always “needed” to solve a problem like this in my life. It’s certainly helpful to determine if an algorithm you are creating is correct, however not all programs and systems require complex algorithms or demand proofs like this to be useful and not all programs require complicated math to begin with. User interfaces, websites, databases, all don’t need to be “mathematically correct” they just need to work well enough. Don’t get me wrong, math can be a huge help, but it’s not always necessary to get the job done.

As a programmer, I'm not gonna deny there is a lot of math used for so many different applications. But for the first puzzle, particularly for those who are just interested in making a little working game in a hurry, there is a really simple and elegant solution to developing random puzzles. Start with a completed puzzle, and have your program "play" it backwards, swapping only pieces that can be legitimately moved, for a random number of iterations before handing it over to the user to solve. You will always end up with a solvable puzzle regardless of size and shape of the board. No math required, and is a technique that can be used for many different types of puzzles.

The actual use for spanning trees to prevent broadcast storms in networks. There might (and probably ought to) be multiple physical connections for a single node, for resiliency in case of problems, but you don't want multiple simultaneous paths for data-link traffic or else your frames (which are often broadcast to all open ports when seeking new addresses) can end up in a chain reaction in infinite loops. So spanning tree protocols identify the optimal connections for the topology and disable redundant links.

@@pumpernickelstickybottoms5081 thats because when people say theyre bad at math, what theyre really saying is theyre bad at computations (which is what is taught in high school), which is like a new language one can practice, but math is about insight, you just need the computation to prove your insight is correct.

@@missionpupa I'm actually the opposite weirdly enough. I'm pretty good with calculations (I always got perfect grades in calculus), but I suck when it comes to the creative/intuitive side of math like proofs. I struggle with problems where I have to find a solution without someone giving me a formula, like the one in the video.

This is more of used in arranging routes for logistics, not in computer science. We have been taught it in Operations Management subject in Engineering.

I think the handshake example needs more clarification on what "9 other people" means. If A shakes hands with everyone, then that's 26 handshakes, which is both more than 9 (so A's required 9 is satisfied), and the total handshake count (243) is decreased by 26. I think what's being asked is actually, "In a room of 27 people, is it possible for each person to shake hands with EXACTLY 9 other people (no more and no less)." In that case, then the answer is no. But if each person can shake hands with more than 9, it's possible for each person to shake hands with "9 other people." To clarify: if there are N people in a room, there are (N * (N-1)) / 2 possible unique handshakes (edges). That is, if there are N nodes (people), then there are (N * (N-1))/2 unique edges that can connect the nodes. In this example, for N people, there needs to be 9*N unique handshakes. So if there are 27 people, that means that 243 (9*27) unique handshakes need to occur, and there's a possibility of 351 unique handshakes. 243 < 351, so possible. But again, that's only if for some node A, if A shakes hands with > 9 other people, A's handshake requirement is satisfied.

[@sarvagyagupta1744]

Hey, Thanks for the video. Really informative. However, I have a question from the puzzle at 9:43. It makes sense that the degree needs to be even for an Euler Tour. But, if we consider 3 outer loops instead of 4, it will form an Euler loop even with odd degree at some nodes. How does that happen?

[@__zwischen__]

What you can draw is a Euler path, meaning that the starting and ending nodes need not to be the same node. In this case, at most 2 nodes can have odd degrees. On the other hand, for a Euler tour to exist, every node must have even degrees, so that the path can form a loop.

@@hishitashah7159 Please believe me when I say this, all you have to do is practice. I’m 27 I’ve went my whole life with the mindset of “being bad at math” to me it literally looked like hieroglyphics. I finished a 3 year contract with active duty army in early June and started studying math…from scratch I had no idea where I was at and ended up in prealgebra. I couldn’t figure out the simplest questions I thought that I made the wrong decision, then one day I just got it and I kept getting better. When I was in school no one really cared if I passed or failed math, not my teacher and not my dad so why should I care..plus it didn’t come to me as easily as English or the other subjects I took. But what I started to understand was math is like learning a language in a way it requires practice and more so understanding, you have to understand what you are looking at to truly begin answering the problem. Whenever I got stuck I’d just look up different was to solve a similar question and apply it to what I’m studying. I actually really love and appreciate math I even ditched my calculator for the most part because I learn better from solving equations mentally it helps me understand how to get the answer. I was in the same boat as you I wanted to major in cs but was super intimidated by the math needed. Now I’m really excited and can’t wait, I start in January. I’ll have to take remedial math first thanks to good ol teenage me 😂 but that’s fine I’ll to where I need one step at a time. You can do it, especially if it’s something that you want!
