max_relative_welfare_points
- negmas.preferences.max_relative_welfare_points(ufuns, frontier, ranges=None, outcome_space=None, issues=None, outcomes=None, eps=1e-12)[source]
Calculates all the points with maximum relative welfare (i.e. sum of improvements above reserved value) on the Pareto frontier of a negotiation.
- Parameters:
ufuns (Sequence[UtilityFunction]) – A list of ufuns to use
frontier (Sequence[tuple[float, …]]) – a list of tuples each giving the utility values at some outcome on the frontier (usually found by
pareto_frontier
) to search withinoutcome_space (OutcomeSpace | None) – The outcome-space to consider
issues (Sequence[Issue] | None) – The issues on which the ufun is defined (outcomes may be passed instead)
outcomes (Sequence[Outcome] | None) – The outcomes on which the ufun is defined (outcomes may be passed instead)
- Returns:
A tuple of utility values at the Nash point
The index of the given frontier corresponding to the Nash point
- Return type:
A list of tuples (empty if cannot be calculated) each consists of
Remarks:
The function searches within the given frontier only.
