#include "probfd/heuristics/probability_aware_pdb_heuristic.h"

Description

The probability-aware PDB heuristic.

Combines multiple projections heuristics. The type of combination is specified by the configuration of the pattern collection generation algorithm.

evaluate()

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

pure virtualinherited

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

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

print_statistics()

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

inlinevirtualinherited

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

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