【Abstract】 Focusing on problem of high complexity, difficult convergence and low accuracy for large-scale, nonlinear dynamic optimization problems in chemical networks, a high-performance optimization strategy is developed based on the original differential game numerical optimization algorithm. The strategy focuses on the initial value generation to ensure the large-scale convergence of the optimization solution. Meanwhile, the strategy also proposes an algorithm to improve the accuracy, and the optimality of the optimization results is guaranteed under increasing the solution accuracy. Finally, the validity of the high-performance optimization strategy is verified with utilizing a typical chemical network as a simulation case.更多还原
