Theoretical and practical complexity estimates for local propagation methods in constraint-based programming applications

Abstract

The issues of efficiency and robustness of local propagation methods in conformity to constraint-based programming applications are discussed. Comparative analysis of known algorithms is given and new combined method is proposed. The method allows solving of wider classes of constraint problems for polynomial time. The results of computational experiments are presented to illustrate the method advantages over traditional algorithms.
