pygambit.gambit.MixedBehaviorProfile.liap_value#

MixedBehaviorProfile.liap_value() → float | Rational#

Returns the Lyapunov value (see [McK91]) of the strategy profile.

The Lyapunov value is a non-negative number which is zero exactly at Nash equilibria.

Changed in version 16.5.0: New implementation of liap_value to clarify the distinction between per-player and per-agent concepts.
