Meyniel's conjecture holds for random d-regular graphs

Combinatorics 2018-09-25 v2

Abstract

In the game of cops and robber, the cops try to capture a robber moving on the vertices of the graph. The minimum number of cops required to win on a given graph GG is called the cop number of GG. The biggest open conjecture in this area is the one of Meyniel, which asserts that for some absolute constant CC, the cop number of every connected graph GG is at most CV(G)C \sqrt{|V(G)|}. In a separate paper, we showed that Meyniel's conjecture holds asymptotically almost surely for the binomial random graph. The result was obtained by showing that the conjecture holds for a general class of graphs with some specific expansion-type properties. In this paper, this deterministic result is used to show that the conjecture holds asymptotically almost surely for random dd-regular graphs when d=d(n)3d = d(n) \ge 3.
