14 unusual facts about Complete


AI-complete

Machine translation, therefore, is believed to be AI-complete: it may require strong AI to be done as well as humans can do it.

Automatic test pattern generation

Since the ATPG problem is NP-complete (by reduction from the Boolean satisfiability problem) there will be cases where patterns exist, but ATPG gives up since it will take an incredibly long time to find them (assuming P≠NP, of course).

Conjunctive normal form

3-SAT is NP-complete (like any other k-SAT problem with k>2) while 2-SAT is known to have solutions in polynomial time.

Decision problem

However, this reduction is more liberal than the standard reduction used in computational complexity (sometimes called polynomial-time many-one reduction); for example, the complexity of the characteristic functions of an NP-complete problem and its co-NP-complete complement is exactly the same even though the underlying decision problems may not be considered equivalent in some typical models of computation.

Full configuration interaction

This is because exact solution of the full CI determinant is NP-complete, so the existence of a polynomial time algorithm is unlikely.

Mahjong solitaire

Playing Mahjong solitaire optimally in the sense to maximize the probability of removing all tiles is PSPACE-complete, and the game gets NP-complete when peeking below tiles is allowed.

NP-complete

The Clay Mathematics Institute is offering a US $1 million reward to anyone who has a formal proof that P=NP or that P≠NP.

Oracle machine

When a language L is complete for some class B, then AL=AB provided that machines in A can execute reductions used in the completeness definition of class B. In particular, since SAT is NP-complete with respect to polynomial time reductions, PSAT=PNP.

Permanent is sharp-P-complete

The computational complexity of the permanent also has some significance in other aspects of complexity theory: it is not known whether NC equals P (informally, whether every polynomially-solvable problem can be solved by a polylogarithmic-time parallel algorithm) and Ketan Mulmuley has suggested an approach to resolving this question that relies on writing the permanent as the determinant of a matrix.

Post correspondence problem

A brute force search solves the problem in time O(2k), but this may be difficult to improve upon, since the problem is NP-complete.

PSPACE-complete

Examples of games that are PSPACE-complete (when generalized so that they can be played on an n × n board) are the games hex and Reversi and the solitaire games Rush Hour, Mahjong, Atomix, and Sokoban.

Sharp-P-complete

Jerrum, Valiant, and Vazirani showed that every #P-complete problem either has an FPRAS, or is essentially impossible to approximate; if there is any polynomial-time algorithm which consistently produces an approximation of a #P-complete problem which is within a polynomial ratio in the size of the input of the exact answer, then that algorithm can be used to construct an FPRAS.

Structural alignment

The optimal "threading" of a protein sequence onto a known structure and the production of an optimal multiple sequence alignment have been shown to be NP-complete.

X-Machine Testing

Complete functional testing methods exploit the specification systematically, generating test-sets which exercise the implemented software system exhaustively, to determine whether it conforms to the specification.
