内容简介：

In dynamical and evolutionary game theory, potential games have attracted much attention because players may use potential functions and gradients to converge towards equilibria points. Potential games, however, are rare. We define Lyapunov games (of which potential games are a special case), in which players may climb Lyapunov functions for convergence. We present conditions guaranteeing convergence in such games, and furthermore show that even Lyapunov games are non-generic, and hence rare, in the space of all games.
