In theoretical computer science, nondeterministic constraint logic is a combinatorial system in which an orientation is given to the edges of a weighted undirected graph, subject to certain constraints. One can change this orientation by steps in which a single edge is reversed, subject to the same constraints. The constraint logic problem and its variants have been proven to be PSPACE-complete to determine whether there exists a sequence of moves that reverses a specified edge and are very useful to show various games and puzzles are PSPACE-hard or PSPACE-complete. This is a form of reversible logic in that each sequence of edge orientation changes can be undone. The hardness of this problem has been used to prove that many games and puzzles have high game complexity. (Wikipedia).

Nondeterministic Property Testing - Laszlo Lovasz
Laszlo Lovasz Eotvos Lorand University, Budapest; Member, School of Mathematics April 17, 2012 A property of finite graphs is called nondeterministically testable if it has a "certificate'' such that once the certificate is specified, its correctness can be verified by random local testing
