Our conclusion is that the algorithm performs extraordinarily well, provided that the nearly dense rows and columns of the matrix have been removed prior to reordering. Thus, we recommend the reordering implementation of Duff and Reid for circuit simulation. The reordering times of typical industrial examples confirm this recommendation.
