MinimizeActionCosts

class unified_planning.model.metrics.MinimizeActionCosts(costs: Dict[Action, Timing | Timepoint | int | float | Fraction | FNode | Fluent | Parameter | Variable | bool | str | Object], default: Timing | Timepoint | int | float | Fraction | FNode | Fluent | Parameter | Variable | bool | str | Object | None = None, environment: Environment | None = None)

Bases: PlanQualityMetric

This metric means that only the Plan minimizing the total cost of the Actions is valid.

The costs for each Action of the problem is stored in this quality metric.

property costs: Dict[Action, FNode]

property default: FNode | None

get_action_cost(action: Action) → FNode | None

Returns the cost of the given Action.

Parameters:

action – The action of which cost must be retrieved.

Returns:

The expression representing the cost of the given action. If the retrieved cost is None it means it is not set and therefore it’s invalid; every action cost MUST be set, either with the cost mapping or with the default.
