[graph measure] In graph theory, entanglement of a directed graph is a number measuring how strongly the cycles of the graph are intertwined. It is defined in terms of a mathematical game in which n cops try to capture a robber, who escapes along the edges of the graph. Similar to other graph measures, such as cycle rank, some algorithmic p...
