evaluate()

template<typename >

virtual value_t probfd::Evaluator< typename >::evaluate ( param_type< State > state ) const

pure virtual

Evaluates the heuristic on a given state and returns the heuristic value.

Implemented in probfd::heuristics::ConstantEvaluator< State >.

print_statistics()

template<typename >

virtual void probfd::Evaluator< typename >::print_statistics ( ) const

inlinevirtual

Prints statistics, e.g. the number of queries made to the interface.

Reimplemented in probfd::heuristics::DeadEndPruningHeuristic, and probfd::heuristics::DeterminizationCostHeuristic.
