Abstract

The problem of the computation of the stochastic matrix G associated with discrete-time quasi-birth-death (QBD) Markov chains is analyzed. We present a shifted cyclic reduction algorithm and show that the speed of convergence of the latter modified algorithm is always faster than that of the original cyclic reduction.
