针对拟P*-映射和P(T,α,β)-映射所对应的非线性互补问题,本文对其解的存在性及有效求解算法进行了研究.文中利用组合同伦方法给出了这两类非线性互补问题存在有界解的构造性证明,并利用预估校正方法对同伦路径进行跟踪,得到了互补问题的解.通过数值算例验证了该算法的有效性.
For the nonlinear complementarity problems with P*-mapping and P(T,α,β)- mapping, we study the existence and effective algorithm of a solution. We give the construc- tive proof of existence of a bounded solution by the homotopy method for this two classes of complementarity problem, and trace the homotopy path by using the predictor-corrector method, obtain a solution of the nonlinear complementarity problems. Numerical examples are presented to show the effectiveness of the algorithm.
