Abstract
We study efficient implementations of the push-relabel method for the maximum flow problem. The resulting codes are faster than the previous codes, and much faster on some problem families. The speedup is due t o the combination of heuristics used in our implementations: we show t hat the highest-level selection strategy gives better results when com bined with both global and gap relabeling heuristics. We also exhibit a family of problems for which the running time of all implementations we consider is quadratic.
