摘要: 利用组合极大熵同伦方法, 研究一般的非凸非线性规划问题. 首先运用极大熵函数将多约束的规划问题转化为单约束规划问题, 然后构造求解单约束规划问题的KKT系统的同伦方程, 得到了求解大型约束规划问题的一种有效路径跟踪方法, 并证明了其大范围收敛性.

Abstract: We utilized the combined maximum entropy homotopy method to solve the general nonconvex nonlinear programming problems. At first, we transformed a programming problem with many constraints into one with a single constraint using the maximum entropy function. Then we constructed a homotopy equ ation to solve the K-K-T system of the programming problems with a single cons traint and hence obtained an efficient pathfollowing method for solving the programming problems with many constraints. At last we gave the proof of its global convergence.

Key words: combined maximum entropy homotopy method, nonconvex no nlinear programming problems, global convergence
