Infinite sequential Nash equilibrium

Stephane Le Roux.

In game theory, the concept of Nash equilibrium reflects the collective stability of some individual strategies chosen by selfish agents. The concept pertains to different classes of games, e.g. the sequential games, where the agents play in turn. Two existing results are relevant here: first, all&nbsp;[&hellip;]

Finite choice, convex choice and finding roots

Stéphane Le Roux ; Arno Pauly.

We investigate choice principles in the Weihrauch lattice for finite sets on the one hand, and convex sets on the other hand. Increasing cardinality and increasing dimension both correspond to increasing Weihrauch degrees. Moreover, we demonstrate that the dimension of convex sets can be&nbsp;[&hellip;]

Games Where You Can Play Optimally with Arena-Independent Finite Memory

Patricia Bouyer ; Stéphane Le Roux ; Youssouf Oualhadj ; Mickael Randour ; Pierre Vandenhove.

For decades, two-player (antagonistic) games on graphs have been a framework of choice for many important problems in theoretical computer science. A notorious one is controller synthesis, which can be rephrased through the game-theoretic metaphor as the quest for a winning strategy of the system in&nbsp;[&hellip;]
