Smoothing Methods for Semidefinite Programs

Christian Kanzow, Universität Würzburg

Using a suitable reformulation of the optimality conditions, we present a smoothing-type method for the solution of semidefinite programs. The method is globally and locally quadratically convergent under suitable assumptions. In particular, the local quadratic rate of convergence can be shown without assuming strict complementarity of the solution. To this end, we need a new nondegeneracy condition which will also be discussed. It turns out that this nondegeneracy condition is weaker than some related assumptions taken from the literature. Some numerical results will also be reported in order to illustrate the numerical behaviour of the method.
