Block SOR for Kronecker structured representations

Buchholz, P.; Dayar, Tuğrul (Elsevier, 2004)

The Kronecker structure of a hierarchical Markovian model (HMM) induces nested block partitionings in the transition matrix of its underlying Markov chain. This paper shows how sparse real Schur factors of certain diagonal ...
Block SOR preconditioned projection methods for Kronecker structured Markovian representations

Buchholz, Peter; Dayar, Tuğrul (SIAM, 2005)

Kronecker structured representations are used to cope with the state space explosion problem in Markovian modeling and analysis. Currently, an open research problem is that of devising strong preconditioners to be used ...
