Abstract: This paper consider the parallel variable distribution (PVD) approach proposed by Ferris and Mangasarian for solving optimization problem. This paper propose to apply the PVD approach to problems with general convex constraints and show that the algorithm converges, provided certain conditions are imposed on the change of secondary variables. In this paper, we choose to use the projected gradient direction for secondary variables and replace the minimization problem with a sufficient descent condition in the parallelization stage.
