Webto ensure the linear convergence rate for some efficient numerical schemes, including the original ADMM proposed by Glowinski and Marrocco in 1975, and the generalized ADMM proposed by Eckstein and Bertsekas in 1992, both are special cases of the generalized PPA and have received wide attention. Some refined conditions weaker WebWe consider the linearly constrained separable convex minimization model, whose objective function is the sum of three convex functions without coupled variables. The generalized …
