Detailed Description

Generic Refinable Object.

This is basically a list of refinable parameters, with other basic common properties such as a name,. etc... This allows optimization/refinement algorithms to access the parameters without knowing what the object really is.

Todo:
Define more clearly which operations are recursive (ie also modify sub-objects).

Constructor & Destructor Documentation

ObjCryst::RefinableObj::RefinableObj ( const bool  internalUseOnly)

Constructor.

Using internalUseOnly=true will avoid registering the the object to any registry, and thus (for example) no display will be created, nor will this object be automatically be saved.

Definition at line 1188 of file RefinableObj.cpp.

ObjCryst::RefinableObj::RefinableObj ( const RefinableObj old)

Defined not implemented...

Should never be called (copying the refinable parameters would allow you to modify the input object). Use the default constructor and RefinableObj::AddPar(RefinableObj&) instead.

Definition at line 1203 of file RefinableObj.cpp.

Member Function Documentation

void ObjCryst::RefinableObj::AddOption ( RefObjOpt opt)
protected

Add an option for this parameter

Definition at line 1973 of file RefinableObj.cpp.

void ObjCryst::RefinableObj::AddPar ( const RefinablePar newRefPar)

Add a refinable parameter.

The parameter is copied, so it need only be allocated temporarily.

Deprecated:
Use the next function, which supplies the parameter as a pointer, and avoids a useless copy.
Note
: if a parameter is added and its name is already used by another, its name will be automatically appended with an ~

Definition at line 1416 of file RefinableObj.cpp.

void ObjCryst::RefinableObj::AddPar ( RefinablePar newRefPar)

Add a refinable parameter.

The parameter is not copied, so it should be allocated in the heap.

Note
: if a parameter is added and its name is already used by another, its name will be automatically appended with an ~

Definition at line 1434 of file RefinableObj.cpp.

void ObjCryst::RefinableObj::AddPar ( RefinableObj newRefParList,
const bool  copyParam = false 
)

Add all the parameters in another RefinableObj.

Parameters are copied, so they should be allocated in the heap.

Warning
If a copy of another RefinableObj parameter list is made, such as in the OptimizationObj class, make sure that upon deletion of this object the parameters will not be destroyed. To do this use RefinableObj::SetDeleteRefParInDestructor(false).
Parameters
copyParamif false (default), then parameters are not copied from the object but just referenced. Use RefinableObj::SetDeleteRefParInDestructor(false) accordingly. If true, then the parameters are copied, so that any modification to the fixed/limited/used attributes do not affect the original parameter. Only the value and the parameter's clock can then be modified by the copied parameter
Note
: if a parameter is added and its name is already used by another, its name will be automatically appended with an ~

Definition at line 1451 of file RefinableObj.cpp.

void ObjCryst::RefinableObj::AddRestraint ( Restraint pNewRestraint)

Add a new restraint.

This returns an iterator pointing to the next Restraint in the vector.

Definition at line 1889 of file RefinableObj.cpp.

void ObjCryst::RefinableObj::AddSubRefObj ( RefinableObj obj)
protected

Add an object in the registry of used objects.

Definition at line 1959 of file RefinableObj.cpp.

void ObjCryst::RefinableObj::BeginGlobalOptRandomMove ( )

Raise a flag, to be sure not to make a random change more than once in each RefinableObj.

This calls recursively all sub-objects.

This is necessary since one object may be included in several others. This must be called before making a random configuration change on a list of objects.

Definition at line 1750 of file RefinableObj.cpp.

void ObjCryst::RefinableObj::BeginOptimization ( const bool  allowApproximations = false,
const bool  enableRestraints = false 
)
virtual

This should be called by any optimization class at the begining of an optimization.

This will also check that everything is ready, eg call the RefinableObj::Prepare() function. This also affects all sub-objects.

Note
this may be called several time for some objects which are used by several other objects, or for nested optimizations (e.g. least-squares optimizations inside a global one).
EndOptimization() must be called at the end of the optimization, the same number of time BeginOptimization() was called !
Parameters
allowApproximationsif true, then the object can use faster but less precise functions during the optimization. This is useful for global optimization not using derivatives.
enableRestraintsxrefitem deprecated 28.

Reimplemented in ObjCryst::PowderPattern, ObjCryst::Molecule, ObjCryst::ScatteringData, ObjCryst::Crystal, ObjCryst::PowderPatternDiffraction, ObjCryst::CellExplorer, ObjCryst::TextureEllipsoid, ObjCryst::PowderPatternBackground, and ObjCryst::TextureMarchDollase.

Definition at line 1661 of file RefinableObj.cpp.

unsigned long ObjCryst::RefinableObj::CreateParamSet ( const string  name = "") const

Save the current set of refined values in a new set.

Parameters
name: the name associated to this set of values. Names should be unique.
Returns
an number identifying the set of saved values.
Warning
: there is no limit to the number of parameters sets, so try to release them when you don't need them.

Definition at line 1503 of file RefinableObj.cpp.

void ObjCryst::RefinableObj::EndOptimization ( )
virtual

This should be called by any optimization class at the end of an optimization.

This also affects all sub-objects.

Note
this may be called several time for some objects which are used by several other objects.

Reimplemented in ObjCryst::Molecule, ObjCryst::ScatteringData, ObjCryst::PowderPatternDiffraction, and ObjCryst::ZScatterer.

Definition at line 1682 of file RefinableObj.cpp.

const void ObjCryst::RefinableObj::EraseAllParamSet ( )

Erase all saved refpar sets.

Definition at line 1572 of file RefinableObj.cpp.

void ObjCryst::RefinableObj::GetGeneGroup ( const RefinableObj obj,
CrystVector_uint &  groupIndex,
unsigned int &  firstGroup 
) const
virtual

Get the gene group assigned to each parameter.

Each parameter (a gene in terms of genetic algorithms) can be assigned to a gene group. Thus when mating two configurations, genes will be exchanged by groups. By default (in the base RefinabeObj class), each parameter is alone in its group. Derived classes can group genes for a better s** life.

The number identifying a gene group only has a meaning in a given object. It can also change on subsequent calls, and thus is not unique.

Parameters
objthe , supplied by an algorithm class (OptimizationObj,..), which contains a list of parameters, some of which (but possibly all or none) are parameters belonging to this object.
groupIndexa vector of unsigned integers, one for each parameter in the input object, giving an unsigned integer value as gene group index. At the beginning this vector should contain only zeros (no group assigned).
firstGroupthis is the number of groups which have already been assigned, plus one. The gene groups returned by this object will start from this value, and increment firstGroup for each gene group used, so that different RefinableObj cannot share a gene group.
Note
this function is not optimized, and should only be called at the beginning of a refinement.

Reimplemented in ObjCryst::PowderPattern, ObjCryst::Crystal, ObjCryst::PowderPatternDiffraction, ObjCryst::ZScatterer, ObjCryst::ScatteringPower, ObjCryst::PowderPatternBackground, and ObjCryst::Atom.

Definition at line 1867 of file RefinableObj.cpp.

REAL ObjCryst::RefinableObj::GetLogLikelihood ( ) const
virtual

Get -log(likelihood) of the current configuration for the object.

By default (no likelihood evaluation available), this is equal to 0.

This call should not be recursive, it is the task of the algorithm to get the sum of likelihoods for all objects invlolved.

Note
contrary to the old "Cost Function" approach, with log(Likelihood) there is no 'choice' of cost function, so that it is the task of the object to give the optimized likelihood (possibly with user options).

Reimplemented in ObjCryst::PowderPattern, ObjCryst::Molecule, ObjCryst::Crystal, ObjCryst::DiffractionDataSingleCrystal, ObjCryst::ZMoveMinimizer, and ObjCryst::PowderPatternBackgroundBayesianMinimiser.

Definition at line 1759 of file RefinableObj.cpp.

std::map< RefinablePar *, CrystVector_REAL > & ObjCryst::RefinableObj::GetLSQ_FullDeriv ( const unsigned int  n,
std::set< RefinablePar * > &  vPar 
)
virtual

Get the first derivative for the LSQ function for each parameter supplied in a list.

Returns
: a map, with a RefinablePar pointer as key, and as value the corresponding derivative vector. Note that the value of the map for the NULL key is the current value for the LSQ function, which is also returned. The map will include derivatives only for parameters which have been supplied in vPar - but if a parameter is listed in vPar and has a null derivative, the returned vecor will be empty.
Warning
: currently in development, to provide faster, analytic derivatives
Note
:ideally, this function should be const - but since numerical derivatives may be used before all analytical formulas are entered, a non-const version is required.
Todo:

Reimplemented in ObjCryst::PowderPattern, and ObjCryst::DiffractionDataSingleCrystal.

Definition at line 1819 of file RefinableObj.cpp.

const CrystVector_REAL & ObjCryst::RefinableObj::GetLSQDeriv ( const unsigned int  n,
RefinablePar par 
)
virtual

Get the first derivative values for the LSQ function, for a given parameter.

Note that the default method in the base RefinableObj class is to use numerical derivatives, so it should be overridden for better precision.

Todo:
This should be a const method, and the given RefPar should be const too...

Reimplemented in ObjCryst::Molecule, and ObjCryst::CellExplorer.

Definition at line 1806 of file RefinableObj.cpp.

long ObjCryst::RefinableObj::GetNbPar ( ) const

Total number of refinable parameter in the object.

Note that some may be actually fixed or even not used !! For refinement use PrepareForRefinement(), NbRefParNotFixed(), and ParNotFixed(i)

Definition at line 1348 of file RefinableObj.cpp.

const CrystVector_REAL & ObjCryst::RefinableObj::GetParamSet ( const unsigned long  setId) const

Access one save refpar set.

Parameters
setId: the number identifying the set.

Definition at line 1550 of file RefinableObj.cpp.

Access one save refpar set.

Parameters
setId: the number identifying the set.

Definition at line 1557 of file RefinableObj.cpp.

REAL ObjCryst::RefinableObj::GetParamSet_ParNotFixedHumanValue ( const unsigned long  setId,
const long  parNumber 
) const

Access the (human) value of one refined parameter in a saved set of parameters.

Parameters
setId: the number identifying the set.
parNumber: the number identifying the parameter in the list of refined parameters
Returns
if parNumber=5 and setId=37, then the returned value will be the value (scaled if it is an angle) value of the 5th not-fixed parameter in the saved set #37.

Definition at line 1564 of file RefinableObj.cpp.

const string & ObjCryst::RefinableObj::GetParamSetName ( const unsigned long  setId) const

Get the name associated to a refpar set.

Parameters
setId: the number identifying the set.

Definition at line 1577 of file RefinableObj.cpp.

RefinablePar & ObjCryst::RefinableObj::GetParNotFixed ( const long  i)

Access all parameters in the order they were inputted, skipping fixed parameters.

Must call PrepareForRefinement() before !

Definition at line 1406 of file RefinableObj.cpp.

const RefinablePar & ObjCryst::RefinableObj::GetParNotFixed ( const long  i) const

Access all parameters in the order they were inputed, skipping fixed parameters.

Must call PrepareForRefinement() before !

Definition at line 1411 of file RefinableObj.cpp.

const RefinableObjClock & ObjCryst::RefinableObj::GetRefParListClock ( ) const

Definition at line 1878 of file RefinableObj.cpp.

REAL ObjCryst::RefinableObj::GetRestraintCost ( ) const
virtual

Get the restraint cost (overall penalty of all restraints)

By default this returns 0, so this must be overloaded by any object which actually uses restraint.

Note
Instead, we could return by default the sum of the restraints, but this is dangerous since we want to have derived objects fully responsible for handling restraints.

Definition at line 1880 of file RefinableObj.cpp.

void ObjCryst::RefinableObj::GlobalOptRandomMove ( const REAL  mutationAmplitude,
const RefParType type = gpRefParTypeObjCryst 
)
virtual

Make a random move of the current configuration.

This is for global optimization algorithms. the moves for each parameter are less than their global optimization step, multiplied by the mutation amplitude.

Warning
: this makes a random move for the parameter declared for this object, and it is the duty of the object to decide whether the included objects should be moved and how. (eg an algorithm should only call for a move with the top object, and this object decides how he and his sub-objects moves). By default (RefinableObj implementation) all included objects are moved recursively.

RefinableObj::

Parameters
mutationAmplitudemultiplier for the maximum move amplitude, for all parameters
typerestrain the change exclusively to parameters of a given type (same type or descendant from this RefParType).

Definition at line 1709 of file RefinableObj.cpp.

void ObjCryst::RefinableObj::RegisterClient ( RefinableObj obj) const
virtual

Definition at line 1527 of file RefinableObj.cpp.

void ObjCryst::RefinableObj::SetApproximationFlag ( const bool  allow)
virtual

Enable or disable numerical approximations.

This can be used for global optimization to get faster calculations. Depending on the type of object, this may do something or not (it does not do anything in a base RefinableObj, except calling this function for all sub-objects).

Note

void ObjCryst::RefinableObj::SetLimitsProportional ( const string &  parName,
const REAL  min,
const REAL  max 
)

Change the limits for a given parameter, proportionnaly to the current value.

min should be < 1. and max > 1.

void ObjCryst::RefinableObj::SetLimitsProportional ( const RefParType type,
const REAL  min,
const REAL  max 
)

Change the limits for a category of parameters, proportionnaly to their current value.

min should be < 1. and max > 1.

void ObjCryst::RefinableObj::SetLimitsRelative ( const string &  parName,
const REAL  min,
const REAL  max 
)

Change the limits for a given parameter, giving relative new limits (eg giving -.1 and +.1 will set new limits at the current value + min and current value + max) Thus min should logically be <0 and max >0.

const REAL  max 
)

Change the limits for a category of parameters, giving relative new limits (eg giving -.1 and +.1 will set new limits at the current value + min and current value + max).

Thus min should logically be <0 and max >0.

void ObjCryst::RefinableObj::TagNewBestConfig ( ) const
virtual

During a global optimization, tells the object that the current config is the latest "best" config.

This can be used by the object to make more intellingent random moves (use with caution: highly experimental !).

Reimplemented in ObjCryst::Molecule, ObjCryst::PowderPatternBackground, and ObjCryst::TextureMarchDollase.

Definition at line 1911 of file RefinableObj.cpp.

void ObjCryst::RefinableObj::UpdateDisplay ( ) const
virtual

If there is an interface, this should be automatically be called each time there is a 'new, significant' configuration to report.

Reimplemented in ObjCryst::Molecule.

void ObjCryst::RefinableObj::XMLInput ( istream &  is,
const XMLCrystTag tag 
)
virtual

Input From stream.

Todo:
Add an bool XMLInputTag(is,tag) function to recognize all the tags from the stream. So that each inherited class can use the XMLInputTag function from its parent (ie take advantage of inheritance). The children class would first try to interpret the tag, then if unsuccessful would pass it to its parent (thus allowing overloading), etc...

Member Data Documentation

ObjRegistry<RefinableObj> ObjCryst::RefinableObj::mClientObjRegistry
mutableprotected

Registry of RefinableObject using this object.

This is mutable so that client can modify it (kludge?)

Definition at line 1258 of file RefinableObj.h.

RefinableObjClock ObjCryst::RefinableObj::mClockMaster
protected

Master clock, which is changed whenever the object has been altered.

It should be parent to all clocks recording changes in derived classes.

Definition at line 1291 of file RefinableObj.h.

bool ObjCryst::RefinableObj::mDeleteRefParInDestructor
protected

If true (the default), then all RefinablePar will be deleted when the the object is deleted.

The opposite option (false) should only be used in RefinableObj holding 'copies' of other objects, such as in algorithms.

Definition at line 1268 of file RefinableObj.h.

std::map< unsigned int,std::map<RefinablePar*, CrystVector_REAL> > ObjCryst::RefinableObj::mLSQ_FullDeriv
mutableprotected

Temporary map to return the derivative of the LSQ function versus a list of parameters.

Several LSQ functions can be stored.

Todo:
In development

Definition at line 1282 of file RefinableObj.h.

CrystVector_REAL ObjCryst::RefinableObj::mLSQDeriv
mutableprotected

Temporary array used to return derivative values of the LSQ function for given parameters.

Definition at line 1276 of file RefinableObj.h.

int ObjCryst::RefinableObj::mOptimizationDepth
protected

Is the object being refined or optimized ? if mOptimizationDepth=0, no optimization is taking place.

mOptimizationDepth>0 indicates the object is being optimized. Values larger than 1 indicate that several level of optimizations are taking place, e.g. one least-square optimization during a global optimization, etc...

Definition at line 1252 of file RefinableObj.h.

ObjRegistry<RefObjOpt> ObjCryst::RefinableObj::mOptionRegistry
protected

List of options for this object.

Note that these are just references, to options allocated by the object, to have a simple global access to all options

Definition at line 1264 of file RefinableObj.h.

bool ObjCryst::RefinableObj::mRandomMoveIsDone
protected

This true is false if RefinableObj::GlobalOptRandomMove() has been called since RefinableObj::BeginGlobalOptRandomMove() was called.

Definition at line 1273 of file RefinableObj.h.

vector<Restraint*> ObjCryst::RefinableObj::mvpRestraint
protected

Vector of pointers to the restraints for this object.

This excludes all RefinablePar declared in RefinableObj::mpRefPar, which also are Restraint.

Definition at line 1232 of file RefinableObj.h.

map<unsigned long,pair<CrystVector_REAL,string> > ObjCryst::RefinableObj::mvpSavedValuesSet
mutableprotected

Map of (index,pointers to arrays) used to save sets of values for all parameters.

Currently there is no limit to the number of saved sets.

This is mutable since creating/storing a param set does not affect the 'real' part of the object.
