probfd::heuristics::LPHeuristic< Derived > Class Template Reference

#include "probfd/heuristics/lp_heuristic.h"

Description

template<typename Derived>
class probfd::heuristics::LPHeuristic< Derived >

Base class for heuristics based on linear programming.

This class uses CRTP and requires the methods:

void update_constraints(const State& state) const;
void reset_constraints(const State& state) const;

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

Member Function Documentation

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.
