What is it about?

We study off-central paths that mimics the behavior of iterates generated by an interior point algorithm to solve a class of optimization problems, namely, semidefinite programs and its generalization - monotone semidefinite linear complementarity problems. We investigate the analyticity behavior of these paths near the optimal solutions to these problems.

Why is it important?

Understand the behavior of these paths will lead to a better understanding on the local rate of convergence of iterates generated by the interior point algorithm.

Perspectives

This is part of a series of works on the local convergence study of interior point iterates by studying their associated paths, which are defined using a system of ordinary differential equations.
