WebWe ﬁrst establish an ergodic convergence rate result of inexact ALM that uses constant penalty pa-rameters or geometrically increasing penalty parameters. Based on the convergence rate result, we apply Nesterov’s optimal ﬁrst-order method on each primal subproblem and estimate the iteration complexity of the inexact ALM.
