Abstract

The pseudo-Grundy index of a graph is the largest number of colors that can be assigned to its edges, such that for every pair of colors i,ji,j, if i<ji < j then every edge colored with color jj is adjacent to at least one edge colored with color ii. This index has been widely studied. A geometric graph is a graph drawn in the plane such that its vertices are points in general position, and its edges are straight-line segments. In this paper, we extend the notion of pseudo-Grundy index for geometric graphs, and present results for complete geometric graphs.
