UnDominated finds dominated strategies, or actions, as appropriate, in a support. The returned support contains only the undominated strategies or actions; if this support is identical to the input support, no strategies or actions were found to be dominated. The following optional parameters may be specified to modify the behavior of the elimination:
strong By default, all weakly dominated strategies or actions are eliminated. If this is specified True, elimination is based on strict dominance.
mixed: By default, elimination is done in pure strategies or actions. If this is specified True, elimination is done by examining mixtures over other strategies or actions. Note that mixed elimination is only implemented for normal form games.
conditional: Dominance computations are conditional on reaching infoset containing the action. For example, a behavior strategy may be strongly dominated conditional on reaching its information set, but only weakly dominated in the entire game. Only relevant for extensive form games.
precision: Default precision is rational. Note that the precision parameter is only applicable for mixed domination. Pure strategy domination always uses rational precision.
