Abstract EN
Smoothed aggregation multigrid method is considered for computing stationary distributions of Markov chains.
A judgement which determines whether to implement the whole aggregation procedure is proposed.
Through this strategy, a large amount of time in the aggregation procedure is saved without affecting the convergence behavior.
Besides this, we explain the shortage and irrationality of the Neighborhood-Based aggregation which is commonly used in multigrid methods.
Then a modified version is presented to remedy and improve it.
Numerical experiments on some typical Markov chain problems are reported to illustrate the performance of these methods.
