A basic searchlight game

A searchlight game is a two-person zero-sum dynamic game of the pursuit-evasion type in which at least one of the two players has a searchlight. A searchlight can be flashed a given number of times within a fixed time period and the objective is to catch the opponent in the region illuminated by the flash. Olsder and Papavassilopoulos instituted the study of these games and, in this paper, we supplement their results, obtaining a closed formula for the value and optimal strategies for the players in their basic game.
