Cuts, Cats, and Complete Graphs

Combinatorics 2024-09-23 v1

Abstract

We introduce the game of Cat Herding, where an omnipresent herder slowly cuts down a graph until an evasive cat player has nowhere to go. The number of cuts made is the score of a game, and we study the score under optimal play. In this paper, we begin by deriving some general results, and then we determine the precise cat number for paths, cycles, stars, and wheels. Finally, we identify an optimal Cat and Herder strategy on complete graphs, while providing both a recurrence and closed form for cat(Kn)cat(K_n).
