prepare_optimistic_search(func_name, executor, state, goal_expr, *, actions=None, action_filter=None, verbose=False, forward_state_variables=True, forward_derived=True)

Prepare for optimistic search.

Parameters:

• func_name (str) – the name of the calling function.

• executor (PDSketchExecutor) – the executor.

• state (State) – the initial state.

• goal_expr (str | ValueOutputExpression) – the goal expression.

• actions (Sequence[OperatorApplier] | None) – the actions to be considered.

• action_filter (Callable[[OperatorApplier], bool]) – the action filter. If None, use all possible actions. It should be a function that takes in an action and returns a boolean.

• verbose (bool) – whether to print verbose information.

• forward_state_variables – whether to forward state variables.

• forward_derived – whether to forward derived variables.

Returns:

the initial state, the goal expression, and the actions to be considered.

Return type:

Tuple[State, ValueOutputExpression, Sequence[OperatorApplier]]
