About infinite strategy sets and $\epsilon$-equilibrium from Game Theory: Analysis of Confilct by Roger Myerson

It doesn't matter whether one uses mixed or pure strategies in that place. If a mixed strategy $\tau_i\in\Delta(C_i)$ leads to a payoff larger than $u_i(\sigma)+\epsilon$, it must put positive ...

Equilibrium of Perturbed Dollar Auction Game - An Example from Game Theory: Analysis of Conflict by Roger Myerson

Let us describe the mixed strategy played by both players 1 and 2 using the probability density function $f$. We say that a pure strategy $x$ is in the support $S$ of a mixed strategy $f$ if $f(x)>...

Nash Equillibrium - Depend On The Opponent's Strategy?

The definition of a NE is not that a player cannot increase his payoff by changing his action, its that he cannot increase his payoff by changing his strategy. A strategy in a repeated game is a "...
