Cops and robbers on oriented toroidal grids (1904.10113v2)
Published 23 Apr 2019 in math.CO and cs.DM
Abstract: The game of cops and robbers is a well-known game played on graphs. In this paper we consider the straight-ahead orientations of 4-regular quadrangulations of the torus and the Klein bottle and we prove that their cop number is bounded by a constant. We also show that the cop number of every k-regularly oriented toroidal grid is at most 13.
