摘要:

考虑带有等式约束的一般非线性规划问题, 先用极大值函数把不等式约束等价地表示为一个不光滑的不等式约束, 并采用凝聚方法把不等式约束函数进行带参数的磨光, 再利用组合同伦内点方法在广义弱法锥条件下, 构造性地证明了广义K-K-T方程解的存在性和凝聚同伦方法的整体收敛性. 数值结果表明该方法是有效的.

Abstract:

We studied the problems of general nonlinear programming with equality constrains. First, the inequality constrain was expressed as an nonsmooth inequality constrain by means of the maxvalue function, then with aggregate technique this constrain was smoothed. With the help of combined homotopy interiorpoint method and the weak normal condition, the existence of solution of the generalized K-K-T equation was verified. The algorithm was proved to be globally convergent. The results of numerical experiments show that the algorithm is effective and convenient.
