Abstract:A novel algorithm,SAT-SAGA,is proposed for solving SAT problems based on the combination of the genetic algorithm and simulated annealing algorithm.The genetic algorithms are served as the main flow of the new algorithms which involve the mechanism of simulated annealing to adjust the optimization population,avoid trapping in local optimum and prevent precocity.The strategy of keeping the best chromosomes prevents the problem of convergence in the evolution iteration.The experimental results show that the S...
Keywords:SAT problem  genetic algorithm  simulated annealing algorithm
