Abstract

In this paper, we develop the wave preflow algorithm for minimum flow. This algorithm is a special implementation of the generic preflow algorithm developed by Ciurea and Ciupala in [11]. It is a hybrid between the FIFO preflow algorithm and the highest-label preflow algorithm for minimum flow. It examines the active nodes in nondecreasing order of their distance labels and the node examination terminates when either the node deficit becomes zero or the node is relabeled. The wave preflow algorithm for minimum flow runs in O(n3) time.
