Feasible payoff set
= Feasible payoff set
{title2=$\operatorname{conv}\{u(a):a\text{ a stage action profile}\}$}
The <convex hull> of the stage game's attainable <payoff> vectors. Public randomization or deterministic sequences with prescribed limiting frequencies produce such average <payoffs>. It can be larger than the set attainable using independent <mixed strategies> in a single stage.
