Adjective . NP-complete (not comparable) (computing theory, of a decision problem) That is both NP (solvable in polynomial time by a non-deterministic Turing machine) and NP-hard (such that any (other) NP problem can be reduced to it in polynomial time)....

Classic Nintendo Games are (NP-)Hard Greg Aloupis Erik D. Demainey Alan Guoyz March 9, 2012 Abstract We prove NP-hardness results for ve of Nintendo’s largest video game franchises: Mario,... NP-Complete - A Rough Guide. This is a rough guide to the meaning of "NP-Complete". It is not intended to be an exact definition, but should help you to understand the concept.

Tron (Bally Midway, 1982) is NP-hard. For the full list and reasoning, see the paper below. That’s clearly been a labour of love for Viglietta, given the title of his paper: “Gaming Is A Hard... •if Problem is NP-hard and problem belongs to NP then it is NP-complete. •Problems are designated "NP-complete" if their solutions can be quickly checked for correctness,

### 2 NP-completeness Proofs 1. The first part of an NP-completeness proof is showing the problem is in NP. 2. The second part is giving a reduction

- NP-Completeness How would you define NP-Complete? They are the “hardest” problems in NP P NP NP-Complete Definition of NP-Complete Q is an NP-Complete problem if: 1) Q is in NP 2) every other NP problem polynomial time reducible to Q Getting Started How do you show that EVERY NP problem reduces to Q? One way would be to already have an NP-Complete problem and just reduce from that …

- hard as every problem in NP. NP X Y1 Y2 Y3 P Y4. NP-completeness and P=NP Theorem If X is NP-complete, then X is solvable in polynomial time if and only if P = NP. Proof. If P = NP, then X can be solved in polytime. Suppose X is solvable in polytime, and let Y be any problem in NP. We can solve Y in polynomial time: reduce it to X. Therefore, every problem in NP has a polytime algorithm and P
- NP-hard: Intuitively these are the problems that are even harder than the NP-complete problems. Note that NP-hard problems do not have to be in NP (they do not have to be decision problems). The
