A self-adaptive trust region method for the extended linear complementarity problems. (English) Zbl 1212.65239
Summary: By using some nonlinear complementarity functions, we reformulate the extended linear complementarity problem as a nonsmooth equation. Then, we propose a self-adaptive trust region algorithm for solving this nonsmooth equation. The novelty of this method is that the trust region radius is controlled by the objective function value which can be adjusted automatically according to the algorithm. The global convergence is obtained under mild conditions and the local superlinear convergence rate is also established under strict complementarity conditions.
