摘要:结合 Josephy-Newton方法,建立了一种不含价值函数的求解非线性互补问题的全局策略.该策略基于外梯度步和Filter技术,提出一个外梯度-Filter算法.此算法中的外梯度步可以减少与最优解之间的距离,从而使该算法具有全局收敛性.在适当的条件下,该算法还具有超线性收敛性.

关键词: 非线性互补问题, Filter技术, Josephy-Newton方法, 外梯度步, 收敛性

Abstract: Combined with the Josephy-Newton method,a new globalization strategy without any merit function was established for nonlinear complementarity problem.The strategy presents an extragradient-filter algorithm based on extragradient step and filter technology.The extragradient step can reduce the distance with the optimal solution of the problem.So the resulting algorithm is globally convergent to a solution.Under natural assumptions,locally superlinear rate of convergence can be obtained.

Key words: nonlinear complementarity problem, filter technology, Josephy-Newton method, extragradient step, convergence
