Branch-and-Cut for Mixed-Integer Nash Equilibrium Problems
Aloïs Duguet, Tobias Harks, Martin Schmidt +1
We study Nash equilibrium problems with mixed-integer variables in which each player solves a mixed-integer optimization problem parameterized by the rivals' strategies. We disting…

Minimal Regret Walras Equilibria for Combinatorial Markets
Aloïs Duguet, Tobias Harks, Martin Schmidt +1
We consider combinatorial multi-item markets and propose the notion of a -regret Walras equilibrium, which is an allocation of items to players and a set of item prices that ac…

Branch-and-Cut for Computing Approximate Equilibria of Mixed-Integer Generalized Nash Games
Aloïs Duguet, Tobias Harks, Martin Schmidt +1
Generalized Nash equilibrium problems with mixed-integer variables constitute an important class of games in which each player solves a mixed-integer optimization problem, where bo…
