| contents | We present a method to compute explicit solutions of parametric Generalized Nash Equilibrium (GNE) problems with convex quadratic cost functions and linear coupling and local constraints. Assuming the parameters only enter the linear terms of the cost functions and constraint right-hand sides, we provide the exact multiparametric solution of the GNE problem. Such a solution enables (i) minimal real-time computation, (ii) inherent interpretability, explainability, and exact enumeration of all multiple equilibria, (iii) determine desired GNE solution types in the case of infinitely-many equilibria, and (iv) zero-shot updates of the GNE solution due to changes of constraint right-hand sides and/or linear costs. In line with explicit Model Predictive Control (MPC) approaches, we apply our method to solve game-theoretic MPC (Receding Horizon Games) explicitly, comparing performance against centralized solvers in a battery charging game and in a toy two-mass spring system control problem. A Python implementation of the algorithms presented in this paper is available on https://github.com/bemporad/nash_mpqp. |
