winwin_level

negmas.preferences.winwin_level(u1, u2, outcomes, max_tests=10000)[source]

Finds the win-win level in these two ufuns.

Parameters:
  • u1 (UtilityFunction) – first utility function

  • u2 (UtilityFunction) – second utility function

Return type:

float

Examples

  • A nonlinear same ufun case

>>> from negmas.preferences.crisp.mapping import MappingUtilityFunction
>>> outcomes = [(_,) for _ in range(10)]
>>> u1 = MappingUtilityFunction(
...     dict(zip(outcomes, np.linspace(1.0, 0.0, len(outcomes), endpoint=True)))
... )
  • A linear strictly zero sum case

>>> outcomes = [(_,) for _ in range(10)]
>>> u1 = MappingUtilityFunction(
...     dict(zip(outcomes, np.linspace(0.0, 1.0, len(outcomes), endpoint=True)))
... )
>>> u2 = MappingUtilityFunction(
...     dict(zip(outcomes, np.linspace(1.0, 0.0, len(outcomes), endpoint=True)))
... )
