- MixedBehaviorProfile.action_regrets#
Returns the regret to playing each action, if all other players play according to the profile, grouped by information set.
The regret is defined as the difference between the payoff of the best-response action and the payoff of the action. Payoffs are computed conditional on reaching the information set. By convention, the regret is always non-negative.
Regret is not defined for the chance player, which takes no decisions; its information sets are excluded.
