Before revision:  We discuss an approach to quantify the improved linear asymptotic convergence factor that is based on computing the optimalasymptotic convergence factor for a stationary version of AA applied to ADMM . Numerical tests show that this allows us to estimate the asymptotic linear convergence factor of AA with finite window size applied to ADMM.
After revision:  We discuss an approach to quantify the improved linear asymptotic convergence factor that is based on computing the optimalasymptotic convergence factor for a stationary version of AA applied to ADMM . Numerical tests show that this allows us to quantify the improved linear asymptotic convergence speed of AA-ADMM as compared to the convergence factor of ADMM used by itself. This way of estimating AA-ADMM convergence speed is useful because there are no known convergence bounds for AA with finite window size applied to ADMM.
