Abstract class for scoring object(s) of type ParticleIndexPair. More...

#include <IMP/PairScore.h>

Inherits IMP::ParticleInputs, and IMP::Object.

Detailed Description

Abstract class for scoring object(s) of type ParticleIndexPair.

PairScore will evaluate the score and derivatives for passed object(s) of type ParticleIndexPair.

Use in conjunction with various restraints such as IMP::container::PairsRestraint or IMP::core::PairRestraint. The restraints couple the score functions with appropriate lists of object(s) of type ParticleIndexPair.

It is possible to call the various evaluate* methods directly, but this is not recommended as they do not ensure that Model invariants (e.g. ScoreStates) are preserved. Use a Restraint or ScoringFunction to score the model instead.

Implementers should check out IMP_PAIR_SCORE_METHODS().

Restraints IMP::PairScore::create_current_decomposition	(	Model *	m,
		const ParticleIndexPair &	vt
	)		const

Decompose this PairScore into a set of currently positive restraints over vt. The scoring function and derivatives should be equal to the current score. The default implementation returns a single restraint with this score bound to vt, or zero restraints if the score equals zero.

virtual Restraints IMP::PairScore::do_create_current_decomposition	(	Model *	m,
		const ParticleIndexPair &	vt
	)		const

protectedvirtual

Override this to return your own decomposition.

Reimplemented in IMP::container::MinimumPairScore.

virtual double IMP::PairScore::evaluate_if_good_index	(	Model *	m,
		const ParticleIndexPair &	vt,
		DerivativeAccumulator *	da,
		double	max
	)		const

virtual

Compute the score and the derivative if needed, only if "good".

This functions similarly to evaluate_index(), but may terminate the computation early if the score is higher than max.

Returns: the score if score<= max or some arbitrary value > max otherwise.

Reimplemented in IMP::core::ClosePairsPairScore, and IMP::core::KClosePairsPairScore.

virtual double IMP::PairScore::evaluate_if_good_indexes	(	Model *	m,
		const ParticleIndexPairs &	o,
		DerivativeAccumulator *	da,
		double	max,
		unsigned int	lower_bound,
		unsigned int	upper_bound
	)		const

virtual

Compute the score and the derivative if needed over a set, only if "good". This functions similarly to evaluate_indexes(), but may terminate the computation early if the total score is higher than max.

Returns: the score if score<= max or some arbitrary value > max otherwise.

Note: An implementation for this is provided by the IMP_PAIR_SCORE_METHODS() macro.

virtual double IMP::PairScore::evaluate_index	(	Model *	m,
		const ParticleIndexPair &	vt,
		DerivativeAccumulator *	da
	)		const

pure virtual

Compute the score and the derivative if needed.

Parameters

m	the model of vt
vt	the index in m of an object of type ParticlePair
da	a DerivativeAccumulator that weights computed derivatives. If nullptr, derivatives will not be computed.

virtual double IMP::PairScore::evaluate_indexes	(	Model *	m,
		const ParticleIndexPairs &	o,
		DerivativeAccumulator *	da,
		unsigned int	lower_bound,
		unsigned int	upper_bound
	)		const

virtual

Compute the score and the derivative if needed over a set.

Parameters

m	the model of o
o	objects of type ParticlePair, specified by index
da	a derivative accumulator that weights computed derivatives. If nullptr, derivatives will not be computed.
lower_bound	index of first item in o to evaluate
upper_bound	index one past last item in o to evaluate

Note: An implementation for this is provided by the IMP_PAIR_SCORE_METHODS() macro.

virtual double IMP::PairScore::evaluate_indexes_delta	(	Model *	m,
		const ParticleIndexPairs &	o,
		DerivativeAccumulator *	da,
		const std::vector< unsigned > &	indexes,
		std::vector< double > &	score
	)		const

virtual

Compute the change in score and the derivative if needed over a set.

The score for each o[indexes[x]] is updated in score[indexes[x]] and the total difference between the old and new score values (over the set) is returned.

Note: An implementation for this is provided by the IMP_PAIR_SCORE_METHODS() macro.

virtual double IMP::PairScore::evaluate_indexes_scores	(	Model *	m,
		const ParticleIndexPairs &	o,
		DerivativeAccumulator *	da,
		unsigned int	lower_bound,
		unsigned int	upper_bound,
		std::vector< double > &	score
	)		const

virtual

Compute the score and the derivative if needed over a set.

Like regular evaluate_indexes(), but the score for each o[x] is also returned as score[x].

Note: An implementation for this is provided by the IMP_PAIR_SCORE_METHODS() macro.
