Hence, to prove the ... WebNP-Complete means that a problem is both NP and NP-Hard. It means that we can verify a solution quickly (NP), but its at least as hard as the hardest problem in NP (NP-Hard). I don't really know what it means for it to be non-deterministic. Non-determinism is an alternative definition of NP.

WebAn NP complete problem is a problem that other problem in NP reduces to. A problem p in NP is NP-complete if every other problem in NP can be transformed (or reduced) into p in polynomial time. if we can solve these problems, we can solve any other NP problem and the solutions to these problems can be verified in polynomial time. WebAnswer (1 of 2): The paper by Fraenkel and Lichtenstein that proves this result (which was a real treat to glance over; more on that in a second) makes a few important assumptions. They define n \times n chess to be chess on an n \times n board (as you would expect), but they don’t make any assum...
