Graph Problems: Hard Problems

2012
A cynical view of graph algorithms is that “everything we want to do is hard.”Indeed, no polynomial-time algorithms are known for any of the problems in this section.All of them are provably NP-complete with the exception of graph isomorphism—whose complexity status remains an open question.
