Abstract

Constraint satisfaction problem is an important issue in the field of artificial intelligence. This paper proposed two algorithms combining belief propagation and simulated annealing to solve a random constraint satisfaction problem with exact phase transitions and large number of hard instances. The algorithms firstly obtained the marginal probability distribution of variable values after the convergence of the belief propagation equation, then used the strategy of maximum probability and minimum component entropy to generate a set of heuristic initial assignments, and then used simulated annealing to modify the assignments. The experimental results show that the algorithms greatly improve the convergence rate from the initial assignments toward the optimal solution, and shows a significant advantage over simulated annealing algorithm.
