Detailed Description

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

SingletonScore will evaluate the score and derivatives for passed object(s) of type ParticleIndex.

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

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_SINGLETON_SCORE().

Restraints IMP::SingletonScore::create_current_decomposition	(	Model *	m,
		ParticleIndex	vt
	)		const

Decompose this SingletonScore 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::SingletonScore::do_create_current_decomposition	(	Model *	m,
		ParticleIndex	vt
	)		const

protectedvirtual

Override this to return your own decomposition.

Reimplemented in IMP::container::MinimumSingletonScore.

virtual double IMP::SingletonScore::evaluate_if_good_index	(	Model *	m,
		ParticleIndex	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.

virtual double IMP::SingletonScore::evaluate_if_good_indexes	(	Model *	m,
		const ParticleIndexes &	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: Implementations for these are provided by the IMP_SINGLETON_SCORE() macro.

virtual double IMP::SingletonScore::evaluate_index	(	Model *	m,
		ParticleIndex	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 Particle
da	a DerivativeAccumulator that weights computed derivatives. If nullptr, derivatives will not be computed.

Implemented in IMP::core::PredicateSingletonScore< Predicate, Score >, IMP::core::SphereDistanceToSingletonScore, IMP::npctransport::HarmonicSpringSingletonScore, IMP::npctransport::ZBiasSingletonScore, IMP::core::GenericDistanceToSingletonScore< UF >, IMP::atom::ImproperSingletonScore, IMP::npctransport::ExcludeZRangeSingletonScore, IMP::core::GenericBoundingSphere3DSingletonScore< UF >, IMP::spb::TiltSingletonScore, IMP::core::GenericBoundingBox3DSingletonScore< UF >, IMP::atom::AngleSingletonScore, IMP::atom::BondSingletonScore, IMP::atom::DihedralSingletonScore, IMP::container::MinimumSingletonScore, IMP::core::GenericAttributeSingletonScore< UF >, and IMP::core::GenericAttributeSingletonScore< core::Harmonic >.

virtual double IMP::SingletonScore::evaluate_indexes	(	Model *	m,
		const ParticleIndexes &	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 Particle, 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: Implementations for these are provided by the IMP_SINGLETON_SCORE() macro.

virtual double IMP::SingletonScore::evaluate_indexes_delta	(	Model *	m,
		const ParticleIndexes &	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.

virtual double IMP::SingletonScore::evaluate_indexes_scores	(	Model *	m,
		const ParticleIndexes &	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].
