Abstract

In this paper, we are concerned with nonlinear minimization problems with second-order cone constraints. A primal-dual interior point method that uses a commutative class of search directions is considered. We propose a new primal-dual merit function by combining the barrier penalty function and the potential function within the framework of the line search strategy, and show the global convergence property of our method.
