NP-hard - Wikipedia, the free encyclopedia
NP-hard (non-deterministic polynomial-time hard), in computational complexity theory, is a class of problems that are, informally, "at least as hard as the hardest problems in NP". A problem H is N...

List of NP-complete problems - Wikipedia, the free encyclopedia
Here are some of the more commonly known problems that are NP-complete when expressed as decision problems. This list is in no way comprehensive (there are more than 3000 known NP-complete problems). ...

there are several so-called NP-hard problems, which most people believe cannot be solved in polynomial time, even though nobody can prove a super-polynomial lower bound. Circuit satisfiability is a good example of a problem that we don't know how to solve in polynomial time.

This is a continuously updated catalog of approximability results for NP optimization problems. The compendium is also a part of the book Complexity and Approximation. The compendium has not been updated for a while, so there might exist recent results that are not mentioned in the compendium.
