comment Finite topologies — what are they good for?
I think this could be a good question if phrased as a reference request.

comment Should I do all the exercises in a textbook?
@Graduate Presumably you attend lectures and follow your professors' advice because they are experts whose opinion you respect, not merely because they happen to have some authority over you.

comment A variation of the menage problem
There being only a modest number of bad cases (the couples sitting together), I wonder if inclusion-exclusion could be made to work. It looks like it could be messy when couples are sitting near the ends of the row, however.

@Mathisthethoughtofcreation Gaining reputation by asking and answering questions gives you some privileges on the website. Badges are just for fun. (They're like videogame achievements, if you are familiar with those.)

comment maximum k-colorable subgraph
If you disregard complexity of a problem, there is always the brute force solution: color every subgraph of $G$ and keep track of the maximum $k$-colorable one. I shudder to think how long this would take on a graph of even twenty vertices.

You might find The Art of Problem Solving a good place to start.
