A general measure of the constrainedness of an ensemble of problems, used to locate phase transitions in random NP-complete problems, predicts the location of a phase transition in establishing arc ... WebIn this paper, we introduce a parameter ( τ) that measures the constrainedness of a search problem. This parameter represents the probability of a problem being feasible. A value of τ = 0 corresponds to an over-constrained problem and no states are expected to be solutions.

WebThis constrainedness parameter generalizes a number of parameters previ- ously used in different NP-complete problem classes. Phase transitions in different NP classes can thus be directly compared. This parameter can also be used in a heuristic to guide search.

WebApr 15, 2008 · In this paper, we present a heuristic technique called constraint ordering heuristic (COH) that can be applied to any backtracking-based search algorithm to solve real problems.
