We reformate a general phase retrieval (PR) problem to explicitly contain a Lipchitz differentiable term. The model can be efficiently solved via Partially Preconditioned Proximal Alternating Linearized Minimization (P3ALM). Thanks to the Lipchitz term, we prove the global convergence of P3ALM. We conduct experiments on a variety of PR sampling schemes to show the effectiveness of the proposed method. Finally, some empirical observations are drawn to better characterize the PR problems.
