Valued Constraint Satisfaction Problems: Hard and Easy Problems

  title={Valued Constraint Satisfaction Problems: Hard and Easy Problems},
  author={Thomas Schiex and H{\'e}l{\`e}ne Fargier and G{\'e}rard Verfaillie},
In order to deal with over-constrained Constraint Satisfaction Problems, various extensions of the CSP framework have been considered by taking into account costs, uncertainties, preferences, priorities...Each extension uses a specific mathematical operator (+;max : : :) to aggregate constraint violations. In this paper, we consider a simple algebraic framework, related to Partial Constraint Satisfaction, which subsumes most of these proposals and use it to characterize existing proposals in… CONTINUE READING
