How to find, or at least express, the equilibrium of a zero-sum game with an $n*n$ payoff matrix (each player has $n$ strategies) and the payoff of the entry $(i,j)$ is $u(i,j)$. $u$ a random function of the strategies $i$ and $j$.
What about the case where $n \rightarrow \infty$.
Any reference or code is welcome.
Thanks a lot!
