Nash Equilibrium
A strategy combination (a,b) is a Nash
equilibrium for two players if neither player
would unilaterally deviate if he expected the
other player to choose according to (a,b). A
strategy combination (a,b,c,) is a Nash
equilibrium for N players if no player would
unilaterally deviate if he expected the other
(N-1) players to choose according to (a,b,c,).
