ensure_os

negmas.outcomes.ensure_os(outcome_space, issues, outcomes) → OutcomeSpace

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 neither is given, a ValueError exception will be raised.

• 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
