A simple multiscale method for mean field games

نویسندگان

چکیده

This paper proposes a multiscale method for solving the numerical solution of mean field games which accelerates convergence and addresses problem determining initial guess. Starting from an approximate at coarsest level, constructs approximations on successively finer grids via alternating sweeping, not only allows use classical time marching schemes, but also enables applications to both local nonlocal problems. At each relaxation is used stabilize iterative process. A second-order discretization scheme derived higher order convergence. Numerical examples are provided demonstrate efficiency proposed in nonlocal, 1-dimensional 2-dimensional cases.

Numerical Method for Bertrand Mean Field Games Using Multigrid

We study dynamic Bertrand mean field games (MFG) with exhaustible capacities in which companies compete with each other using the price as the strategic variable and the interaction among the competition is through the average price. We consider both continuum mean field games and finite player games. Dynamic continuum mean field games can be modeled as a system of partial differential equation...

Mean-Field Games for Marriage

This article examines mean-field games for marriage. The results support the argument that optimizing the long-term well-being through effort and social feeling state distribution (mean-field) will help to stabilize marriage. However, if the cost of effort is very high, the couple fluctuates in a bad feeling state or the marriage breaks down. We then examine the influence of society on a couple...

Mean Field Games

We survey here some recent studies concerning what we call mean-field models by analogy with Statistical Mechanics and Physics. More precisely, we present three examples of our mean-field approach to modelling in Economics and Finance (or other related subjects. . . ). Roughly speaking, we are concerned with situations that involve a very large number of “rational players” with a limited inform...

Discrete mean field games

In this paper we study a mean field model for discrete time, finite number of states, dynamic games. These models arise in situations that involve a very large number of agents moving from state to state according to certain optimality criteria. The mean field approach for optimal control and differential games (continuous state and time) was introduced by Lasry and Lions [LL06a, LL06b, LL07]. ...

Central Schemes for Mean Field Games∗

Mean field type models have been recently introduced and analyzed by Lasry and Lions. They describe a limiting behavior of stochastic differential games as the number of players tends to infinity. Numerical methods for the approximation of such models have been developed by Achdou, Camilli, Capuzzo-Dolcetta, Gueant, and others. Efficient algorithms for such problems require special efforts and ...
