PartialOrderPlan

class unified_planning.plans.PartialOrderPlan(adjacency_list: Dict[ActionInstance, List[ActionInstance]], environment: Environment | None = None, _graph: DiGraph | None = None)[source]

Bases: Plan

Represents a partial order plan. Actions are represent as an adjacency list graph.

property get_adjacency_list: Dict[ActionInstance, List[ActionInstance]]: Returns the graph of action instances as an adjacency list.

replace_action_instances(replace_function: Callable[[ActionInstance], ActionInstance | None]) → Plan[source]

Returns a new PartialOrderPlan where every ActionInstance of the current plan is replaced using the given replace_function.

Parameters:: replace_function – The function that applied to an ActionInstance A returns the ActionInstance B; B replaces A in the resulting Plan.
Returns:: The PartialOrderPlan where every ActionInstance is replaced using the given replace_function.

convert_to(plan_kind: PlanKind, problem: AbstractProblem) → Plan[source]

This function takes a PlanKind and returns the representation of self in the given plan_kind. If the conversion does not make sense, raises an exception.

For the conversion to SequentialPlan, returns one all possible SequentialPlans that respects the ordering constraints given by this PartialOrderPlan.

Parameters:

plan_kind – The plan_kind of the returned plan.
problem – The Problem of which this plan is referring to.

Returns:

The plan equivalent to self but represented in the kind of plan_kind.

all_sequential_plans() → Iterator[SequentialPlan][source]: Returns all possible SequentialPlans that respects the ordering constraints given by this PartialOrderPlan.

get_neighbors(action_instance: ActionInstance) → Iterator[ActionInstance][source]

Returns an Iterator over all the neighbors of the given ActionInstance.

Parameters:: action_instance – The ActionInstance of which neighbors must be retrieved.
Returns:: The Iterator over all the neighbors of the given action_instance.

property environment: Environment: Return this plan’s Environment.

property kind: PlanKind: Returns the Plan kind
