This paper is concerned with applying bandwidth and profile reduction reordering algorithms prior to computing an incomplete Cholesky factorization and using this as a preconditioner for the conjugate gradient method. Hundreds of reordering algorithm

Hundreds of heuristics have been proposed to resolve the problems of bandwidth and profile reductions since the 1960s. We found 132 heuristics that have been applied to these problems in reviews of the literature. Among them, 14 were selected for whi

This paper evaluates the original Hager’s adjacent exchange methods in conjunction with heuristics for bandwidth and profile reductions with the objective of reducing computing times of the zero–fill incomplete Cholesky–preconditioned conjugate

This paper presents a variant of Snay’s algorithm for profile reduction of matrices. The new heuristic for profile reduction shows better results when compared with the results of several reordering algorithms with regards to reducing the computati

Previous publications analyzed a large number of heuristics for bandwidth and profile reductions, and 14 heuristics were selected as promising low-cost heuristics for these problems. Based on extensive numerical experiments, this paper evaluates thes

Several heuristics for bandwidth and profile reductions have been proposed since the 1960s. In systematic reviews, 133 heuristics applied to these problems have been found. The results of these heuristics have been analyzed so that, among them, 13 we
