Abstract: In this paper, the nonconvex global optimization problem with linear constraints is studied. Based on the effective set algorithm, a stochastic differential equation algorithm with stochastic diffusion properties is proposed. The theoretical properties and convergence of the algorithm are discussed. It is proved that the algorithm converges to the global optimal solution of the problem with probability 1. Finally, the numerical experiment results are listed.
