Abstract: In this paper, we propose a general alternating proximal gradient method for linear constrained convex optimization problems with the objective containing two separable functions. Our method is based on the framework of alternating direction method of multipliers. The global and linear convergence of the proposed method is established under certain conditions. Numerical experiments show that the algorithm has good numerical performance.

Key words: alternating direction method of multipliers, general alternating proximal gradient method, global convergence, Q-linear convergence
