Hongwei Niu, Yanchao Yin, Binlei Chang · 2017
Aiming at the problem of premature convergence for particle swarm optimization (PSO) algorithm, a multi populations cooperative search algorithm based on undirected weighted graph is proposed to improve the accuracy of optimization. Then the evolution model of multi populations cooperative network is established on the basis of undirected weighted graph and a multi populations bidirectional interactive pattern is constructed, whose asynchronous parallel search algorithm is given at the same time. Finally experimental results on several benchmark function show that the presented algorithm can rapidly converge at very high quality solutions.
