Abstract

According to the slow convergence and easiness to trap in local optimum of backtracking search optimization algorithm, this paper presented an improved algorithm. The method proposed a mutation scale factor based on t distribution firstly to speed up the convergence rate. Then the algorithm improved the structure of crossover equation and introduced the optimal individual to control the direction of population search, which effectively improved the development capability. Finally, the algorithm proposed the evolutionary selection mechanism, introduced the mutation factor of differential evolution algorithm and replaced the optimal solution with worse solution under a certain probability, which can avoid algorithm to fall into the local optimum. The numerical experiments selected 15 test functions for simulation and compared with 5 well-behaved algorithms. The results show that the proposed algorithm has obvious advantages in terms of convergence rate and search accuracy.
