Joint dominance of payoff vectors
= Joint dominance of payoff vectors
{title2=$u'\ge u,\quad u'\ne u$}
A feasible <payoff> <vector> $u'$ jointly dominates $u$ if every coordinate is at least as large and at least one is strictly larger. A <Pareto optimal> <vector> has no feasible joint dominator. Strict increase of every coordinate is not required. This compares each player's own utilities, not the numerical size of utilities across different players.
