Are there good online videos for Combinatorics?

Question

I am currently reading through "Walk Through Combinatorics" and encountered some difficult concepts and was wondering if there were online videos/lectures/courses that would help in learning the material.

A simple google search results in many good resources. For example Khan academy : https://www.khanacademy.org/computing/pixar/crowds/crowds-1/v/intro-crowds If you have any specific questions about the material, now thats when you should post here :) Good luck!

Answer 2

You could try these for enumerative combinatorics, these and these for extremal combinatorics, maybe these for graph theory
