On the Nash Equilibria of a Simple Discounted Duel
Athanasios Kehagias
We formulate and study a two-player static duel game as a nonzero-sum discounted stochastic game. Players are standing in place and, in each turn, one or both may sho…
An Algorithm for Limited Visibility Graph Searching
Ath. Kehagias, A. C. Papazoglou
We study a graph search problem in which a team of searchers attempts to find a mobile target located in a graph. Assuming that (a) the visibility field of the searchers is limited…
Some Game Theoretic Remarks on Two-Player Generalized Cops and Robbers Games
Athanasios Kehagias, Georgios Konstantinidis
In this paper we study the two-player generalized Cops and Robber (GCR) games introduced by Bonato and MacGillivray. Our main goal is to present a full, self-contained game theoret…
On positionality of trigger strategies Nash Equilibria in SCAR
George Konstantinidis, Athanasios Kehagias
We study the positionality of \emph{trigger strategies} Nash equilibria for the -player SCAR games (with ). Our study is exha…
A Note on the Nash Equilibria of Some Multi-Player Reachability / Safety Games
Athanasios Kehagias
In this short note we study a class of multi-player, turn-based games with deterministic state transitions and reachability / safety objectives (this class contains as special case…
Selfish Cops and Active Robber: Multi-Player Pursuit Evasion on Graphs
G. Konstantinidis, Ath. Kehagias
We introduce and study the game of "Selfish Cops and Active Robber" (SCAR) which can be seen as an multiplayer variant of the "classic" two-player Cops and Robbers (CR) game. In cl…
