os_or_none

negmas.outcomes.os_or_none(outcome_space, issues, outcomes) → OutcomeSpace | None

Returns an outcome space from either an outcome-space, a list of issues, a list of outcomes, or the number of outcomes

Remakrs:

• Precedence is in the order of paramters outcome_space > issues > outcomes.

• If nothing is given, it will just return None

• Will not copy the outcome-space if it is given

• A CartesianOutcomeSpace will be created if an outcome-space is not given

• If outcomes is given or all issues are discrete, a DiscreteCartesianOutcomeSpace will be created
