WebJan 31, 2015 · 1. A (pure strategy) nash equilibrium can still involve strategies that are weakly dominated. However, a nash equilibrium cannot involve a strategy that is strictly dominated by another. On the other hand, a dominant strategy equilibrium is when all players play a strictly dominant strategy. A nash equilibrium does not imply that both … WebMar 9, 2024 · The term Nash-equilibrium applies to the set of strategies taken by all the players, not to any one player’s individual strategy. If a player can only do worse by deviating then the equilibrium is strict, if she can do just as well (but no better) then then the equilibrium is weak, and if she can do better, then it is not an equilibrium. The ...
