#include "probfd/heuristics/determinization_cost.h"

Inheritance diagram for probfd::heuristics::DeterminizationCostHeuristic:

Description

Uses a classical heuristic on the all-outcomes-determinization to estimate the expected costs to reach the goal.

Note

If the underlying classical heuristic is admissible/consistent, this heuristic is also admissible/heuristic.

Public Member Functions
	DeterminizationCostHeuristic (std::shared_ptr<::Evaluator > heuristic)

void	print_statistics () const override
	Prints statistics, e.g. the number of queries made to the interface.
virtual value_t	evaluate (param_type< State > state) const=0
	Evaluates the heuristic on a given state and returns the heuristic value.
