Web2 Analysis of the Push-Relabel Algorithm We begin by showing that no vertex can reach a height bigger than 2 jVj 1. This automatically puts an upper bound to the number of relabel operations that can be executed, and is an important starting point in analyzing the number of push operations. Lemma 2 At every step, if a vertex vhas positive excess WebNov 22, 2004 · Notably, in 2008, Hochbaum published a pseudoflow algorithm [4], which was demonstrated to be more efficient than the LG and other prevalent maximum flow algorithms, such as the Push-Relabel ...
