Inheritance diagram for IMP::OptimizerState:

Detailed Description

Shared optimizer state that is invoked upon commitment of new coordinates.

An OptimizerState update() method is called every time that an owning Optimizer commits to a new set of coordinates. The update() method, in turn, invokes do_update(), which can be overridden by inheriting classes.

Note

An OptimizerState may have periodicity by its set_period() method

An OptimizerState is added to an Optimizer object by calling Optimizer::add_optimizer_state().

Optimizer states may change the values of particle attributes. However, changes to whether an attribute is optimized or not may not be picked up by the Optimizer until the next call to optimize.

When logging is VERBOSE, state should print enough information in evaluate to reproduce the the entire flow of data in update. When logging is TERSE the restraint should print out only a constant number of lines per update call.

Constructor & Destructor Documentation

IMP::OptimizerState::OptimizerState	(	Model *	m,
		std::string	name
	)

constructs an optimizer state whose update() method is invoked every time that a set of model coordinates is committed by an optimizer.

Parameters

m	the model to which this optimizer state is associated
name	the name of the object

Note

An optimizer state may become periodic via its set_period() method.

Member Function Documentation

virtual ModelObjectsTemp IMP::OptimizerState::do_get_inputs ( ) const

protectedvirtual

Get any Particle, Container or other ModelObjects read by this during evaluation. If you read everything in a container, you can just return that container.

Implements IMP::ModelObject.

Reimplemented in IMP::atom::WritePDBOptimizerState.

Definition at line 123 of file OptimizerState.h.

virtual ModelObjectsTemp IMP::OptimizerState::do_get_outputs ( ) const

protectedvirtual

Get any Particle, Container or other ModelObjects changed by this during evaluation. This is only useful for ScoreStates, at the moment.

Implements IMP::ModelObject.

Definition at line 126 of file OptimizerState.h.

virtual void IMP::OptimizerState::do_update ( unsigned int  )

protectedvirtual

This method is called every get_period() update calls. The number of times this method has been called since the last reset or start of the optimization run is passed.

Reimplemented in IMP::atom::WritePDBOptimizerState, IMP::atom::BerendsenThermostatOptimizerState, IMP::SaveToConfigurationSetOptimizerState, IMP::rmf::SaveOptimizerState, IMP::atom::LangevinThermostatOptimizerState, IMP::misc::DecayPairContainerOptimizerState, IMP::atom::VelocityScalingOptimizerState, IMP::atom::RemoveTranslationOptimizerState, IMP::atom::RemoveRigidMotionOptimizerState, IMP::core::WriteRestraintScoresOptimizerState, and IMP::display::WriteOptimizerState.

unsigned int IMP::OptimizerState::get_number_of_updates

(

)

const

Return the number of times update has been called.

Definition at line 108 of file OptimizerState.h.

unsigned int IMP::OptimizerState::get_period

(

)

const

Returns

the periodicity of the optimizer (how many calls to update() are required to invoke do_update()

Definition at line 97 of file OptimizerState.h.

virtual void IMP::OptimizerState::reset ( )

virtual

Reset the phase to 0 and set the call number to 0 too.

virtual void IMP::OptimizerState::set_is_optimizing ( bool  )

virtual

Called with true at the beginning of an optimizing run and with false at the end.

Note

Do not override, override do_set_is_optimizing() instead.

void IMP::OptimizerState::set_number_of_updates

(

unsigned int

n

)

Set the counter.

Definition at line 111 of file OptimizerState.h.

void IMP::OptimizerState::set_period

(

unsigned int

p

)

Causes update() invoke do_update() only every p calls to update() instead of the default p=1. Note that this periodicity is shared by all optimizers that own this OptimizerState object.

Parameters

p	periodicity

virtual void IMP::OptimizerState::update ( )

virtual

Called when the Optimizer accepts a new conformation.

This method is called by owning optimizers every time they commit. However, if set_period(p) was invoked, it calls do_update() only every p times it is called (by any optimizer).

Note

Overriding this method is deprecated, override do_update() instead.

Reimplemented in IMP::container::PairsOptimizerState, IMP::container::QuadsOptimizerState, IMP::container::SingletonsOptimizerState, IMP::container::TripletsOptimizerState, IMP::container::EventPairsOptimizerState, IMP::container::EventQuadsOptimizerState, IMP::container::EventSingletonsOptimizerState, and IMP::container::EventTripletsOptimizerState.

void IMP::OptimizerState::update_always

(

)

Force the optimizer state to perform its action now, ignoring the phase.
