Maximum directed cuts in acyclic digraphs

Abstract

It is easily shown that every digraph with m edges has a directed cut of size at least m/4, and that 1/4 cannot be replaced by any larger constant. We investigate the size of the largest directed cut in acyclic digraphs, and prove a number of related results concerning cuts in digraphs and acyclic digraphs. © 2006 Wiley Periodicals, Inc.
