A bandwidth reduction algorithm for L-shaped and Z-shaped grid structured graphs

摘要

In this paper, a viable bandwidth reduction algorithm based on graphs for reducing the bandwidth of sparse symmetric matrices, arising from standard L-structured and Z-structured graphs, is presented. Bandwidth results for these matrices are obtained using this algorithm and compared with that of existing algorithms. This algorithm can easily be applied to these matrices while the bandwidths obtained are as good as those obtained with the existing algorithms.
