Local convergence of interior-point algorithms for degenerate LCP

Conference ·
OSTI ID:36295

Most asymptotic convergence analysis of interior-point algorithms for monotone linear complementarily problems assumes that the problem is nondegenerate, that is, the solution set contains a strictly complementary solution. We investigate the behavior of these algorithms when this assumption is removed. We show that a large class of infeasible-interior point algorithms can not achieve superlinear convergence when the LCP is degenerate. We also give a feasible interior-point algorithm for degenerate monotone LCP with a reasonable linear rate, depending on the {open_quotes}size{close_quotes} of the degeneracy.
