Abstract

An infeasible interior-point algorithm for solving the
$P_*$-matrix linear complementarity problem based on a kernel
function with trigonometric barrier term is analyzed. Each (main)
iteration of the algorithm consists of a feasibility step and
several centrality steps, whose feasibility step is induced by a
trigonometric kernel function. The complexity result coincides with
the best result for infeasible interior-point methods for
$P_*$-matrix linear complementarity problem.
