Pro tip. When attempting to determine whether a graph is bipartite or not, if two vertices are connected by an edge, due to the definition of a bipartite graph, these two vertices have to be in different sets, and thus, you can colour code them differently. Continue this trend through the graph. If you find a contradiction where two vertices that are connected by an edge are of the same colour, then the graph is not a bipartite graph. Similarly, the opposite can be said to claim that a graph is bipartite.

Wow. Thanks for making this so clear. I thought I was missing something in how you can 'see' that a graph is bipartite. I could do that, but seeing it drawn out as two disjoint sets made it easier to grasp conceptually.

Excellent as usual. Could you also compose a video on the Bipartite Theorem, i.e. "graph is bipartite iff there are no odd cycles". Whilst the first part is straight forward, I find the second part of this theorem somewhat difficult to visualise/understand, i.e. proving that if there are no odd cycles, then graph is bipartite. Just a thought!

@WrathofMath3 жыл бұрын
Thanks for the question, and it depends! Do you mean labeled bipartite graphs? If so, the problem has a fairly straightforward solution, which I may do a lesson on soon. If you asking about unlabeled bipartite graphs (so we would be counting the bipartite graphs that are distinct up to isomorphism), the problem is a good deal more tricky, and I am not sure if there is such a nice formula for it.

Hey I know that one way to determine if a graph is bipartite is by making sure its chromatic number is 2; but I also want to know how to do it by hand. In that case, how do I know how to EXACTLY partition the vertex sets? Also, I have a question; kzbin.info/www/bejne/ioerfWqbobOgb9U --> When I coloured the second graph in this video, it didn't have a chromatic number of 2. Could someone please explain?
