Optimal allocation of ground station data transmission resources based on variable neighborhood estimation of distribution algorithms

Three constrained optimization models were built based on the analysis of influence factors in the problem of optimal allocation of ground station data transmission resources,and a hybrid method which combines estimation of distribution algorithms with variable neighborhood searching(VNS-EDAs) was proposed.Neighborhood structures that can avoid premature convergence were designed in both probability distribution level and population individual level to improve the capability of global exploitation and local...
