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().; An OptimizerState 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 Optimizer::optimize().; When logging is VERBOSE, the state should print enough information in update() to reproduce the entire flow of data in update. When logging is TERSE the state should print out only a constant number of lines per update call.

Constructor & Destructor Documentation

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

Constructor.

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 OptimizerState 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 124 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 127 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.

Definition at line 120 of file OptimizerState.h.

unsigned int IMP::OptimizerState::get_number_of_updates ( ) const

Return the number of times do_update() has been called.

Definition at line 109 of file OptimizerState.h.

unsigned int IMP::OptimizerState::get_period ( ) const

Get the periodicity of this state.

Returns: the periodicity of this state (how many calls to update() are required to invoke do_update())

Definition at line 100 of file OptimizerState.h.

virtual void IMP::OptimizerState::reset ( )

virtual

Reset counters, as if at the start of an optimize run.

Reimplemented in IMP::npctransport::BipartitePairsStatisticsOptimizerState, IMP::npctransport::ChainStatisticsOptimizerState, IMP::npctransport::ParticleTransportStatisticsOptimizerState, IMP::npctransport::BodyStatisticsOptimizerState, and IMP::npctransport::GlobalStatisticsOptimizerState.

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

virtual

Called by an Optimizer to signal begin/end of an optimize run.

At the beginning of an optimize run, set_is_optimizing(true) is called. At the end, set_is_optimizing(false) is called.

Note: Do not override; override do_set_is_optimizing() instead.

void IMP::OptimizerState::set_number_of_updates ( unsigned int n )

Set the counter of number of times do_update() has been called.

Definition at line 112 of file OptimizerState.h.

void IMP::OptimizerState::set_period ( unsigned int p )

Set the periodicity of this state.

This causes update() to invoke do_update() only every p calls to update() rather than on every call (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 state to perform its action now, ignoring the periodicity.
