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 (   )

Constructor.

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.

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.

virtual ObjCryst::RefinableObj::~RefinableObj (   )  [virtual]

Destructor.

---

Member Function Documentation

void ObjCryst::RefinableObj::AddOption (  RefObjOpt *  opt  )  [protected]

Add an option for this parameter.

void ObjCryst::RefinableObj::AddPar (  RefinableObj &  newRefParList  )

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).

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

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

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.

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

Add a new restraint. This returns an iterator pointing to the next Restraint in the vector.

void ObjCryst::RefinableObj::AddSubRefObj (  RefinableObj &   )  [protected]

Add an object in the registry of used objects.

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.

virtual 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. Parameters: allowApproximations:  if true, then the object can use faster but less precise functions during the optimization. This is useful for global optimization not using derivatives. enableRestraints:  if true, then restrained parameters will be allowed to go beyond theur hard limits. This implies that the algorithm will take into account the cost (penalty) related to the restraints. Objects which do not use restraints will simply ignore this. WARNING: this parameter may be removed with the new likelihood scheme. Reimplemented in ObjCryst::Crystal, ObjCryst::Molecule, ObjCryst::PowderPatternDiffraction, ObjCryst::PowderPattern, ObjCryst::TextureMarchDollase, and ObjCryst::ScatteringData.

void ObjCryst::RefinableObj::ClearParamSet (  const unsigned long  id  )  const

Erase the param set with the given id, releasing memory.

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.

virtual void ObjCryst::RefinableObj::DeRegisterClient (  RefinableObj &   )  const [virtual]

Deregister an object (which not any more) using this object.

virtual 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::PowderPatternDiffraction, ObjCryst::ScatteringData, and ObjCryst::ZScatterer.

const void ObjCryst::RefinableObj::EraseAllParamSet (   )

Erase all saved refpar sets.

long ObjCryst::RefinableObj::FindPar (  const REAL *   )  const [protected]

Find a refinable parameter from the adress of its value.

long ObjCryst::RefinableObj::FindPar (  const string &  name  )  const [protected]

Find a refinable parameter with a given name.

map<unsigned long,pair<CrystVector_REAL,string> >::iterator ObjCryst::RefinableObj::FindParamSet (  unsigned long  id  )  const [protected]

Find a parameter set with a given id (and check if it is there).

void ObjCryst::RefinableObj::FixAllPar (   )

Fix All parameters.

virtual const string& ObjCryst::RefinableObj::GetClassName (   )  const [virtual]

Name for this class ("RefinableObj", "Crystal",...). This is only useful to distinguish different classes when picking up objects from the RefinableObj Global Registry Reimplemented in ObjCryst::Atom, ObjCryst::Crystal, ObjCryst::DiffractionDataSingleCrystal, ObjCryst::Molecule, ObjCryst::PowderPatternComponent, ObjCryst::PowderPatternBackground, ObjCryst::PowderPatternDiffraction, ObjCryst::PowderPattern, ObjCryst::PowderPatternBackgroundBayesianMinimiser, ObjCryst::ReflectionProfilePseudoVoigt, ObjCryst::ReflectionProfileDoubleExponentialPseudoVoigt, ObjCryst::Scatterer, ObjCryst::TextureMarchDollase, ObjCryst::Radiation, ObjCryst::ScatteringPower, ObjCryst::ScatteringPowerAtom, ObjCryst::ScatteringPowerSphere, ObjCryst::UnitCell, and ObjCryst::ZScatterer.

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

This clocks records _any_ change in the object. See refinableObj::mClockMaster.

virtual 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: obj  the , 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. groupIndex  a 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). firstGroup  this 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::Atom, ObjCryst::Crystal, ObjCryst::PowderPatternBackground, ObjCryst::PowderPatternDiffraction, ObjCryst::PowderPattern, ObjCryst::ScatteringPower, and ObjCryst::ZScatterer.

virtual 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). Warning: : this is in under heavy development, so expect changes... Reimplemented in ObjCryst::Crystal, ObjCryst::DiffractionDataSingleCrystal, ObjCryst::Molecule, ObjCryst::PowderPattern, ObjCryst::PowderPatternBackgroundBayesianMinimiser, and ObjCryst::ZMoveMinimizer.

virtual const CrystVector_REAL& ObjCryst::RefinableObj::GetLSQCalc (  const unsigned  int  )  const [virtual]

Get the current calculated value for the LSQ function. Reimplemented in ObjCryst::DiffractionDataSingleCrystal, and ObjCryst::PowderPattern.

virtual const CrystVector_REAL& ObjCryst::RefinableObj::GetLSQDeriv (  const unsigned  int, RefinablePar &  )  [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...

virtual const CrystVector_REAL& ObjCryst::RefinableObj::GetLSQObs (  const unsigned  int  )  const [virtual]

Get the observed values for the LSQ function. Reimplemented in ObjCryst::DiffractionDataSingleCrystal, and ObjCryst::PowderPattern.

virtual 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: mutationAmplitude:  multiplier for the maximum move amplitude, for all parameters type:  restrain the change exclusively to parameters of a given type (same type or descendant from this RefParType).

Change the limits for a category of parameters, proportionnaly to their current value. min should be < 1. and max > 1.

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::SetLimitsRelative (  const RefParType *  type, const REAL  min, 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::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.

virtual void ObjCryst::RefinableObj::SetName (  const string &  name  )  [virtual]

Name of the object.

void ObjCryst::RefinableObj::SetParIsFixed (  const RefParType *  type, const bool  fix )

Fix/un-fix one family of parameters.

void ObjCryst::RefinableObj::SetParIsFixed (  const string &  parName, const bool  fix )

Fix/un-fix one parameter from its name.

void ObjCryst::RefinableObj::SetParIsFixed (  const long  parIndex, const bool  fix )

Fix/un-fix one parameter from its #.

void ObjCryst::RefinableObj::SetParIsUsed (  const RefParType *  type, const bool  use )

Set whether a family of parameters is used.

void ObjCryst::RefinableObj::SetParIsUsed (  const string &  parName, const bool  use )

Set whether a parameter is used.

virtual 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.

void ObjCryst::RefinableObj::UnFixAllPar (   )

UnFix All parameters.

virtual 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.

virtual 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... Reimplemented in ObjCryst::Atom, ObjCryst::Crystal, ObjCryst::DiffractionDataSingleCrystal, ObjCryst::Molecule, ObjCryst::PowderPatternBackground, ObjCryst::PowderPatternDiffraction, ObjCryst::PowderPattern, ObjCryst::ReflectionProfile, ObjCryst::ReflectionProfilePseudoVoigt, ObjCryst::ReflectionProfileDoubleExponentialPseudoVoigt, ObjCryst::TextureMarchDollase, ObjCryst::Radiation, ObjCryst::ScatteringPowerAtom, ObjCryst::ScatteringPowerSphere, and ObjCryst::ZScatterer.

virtual void ObjCryst::RefinableObj::XMLOutput (  ostream &  os, int  indent = 0 )  const [virtual]

Output to stream in well-formed XML. Todo: Use inheritance.. as for XMLInputTag()... Reimplemented in ObjCryst::Atom, ObjCryst::Crystal, ObjCryst::DiffractionDataSingleCrystal, ObjCryst::Molecule, ObjCryst::PowderPatternBackground, ObjCryst::PowderPatternDiffraction, ObjCryst::PowderPattern, ObjCryst::ReflectionProfile, ObjCryst::ReflectionProfilePseudoVoigt, ObjCryst::ReflectionProfileDoubleExponentialPseudoVoigt, ObjCryst::TextureMarchDollase, ObjCryst::Radiation, ObjCryst::ScatteringPowerAtom, ObjCryst::ScatteringPowerSphere, and ObjCryst::ZScatterer.

Member Data Documentation

ObjRegistry<RefinableObj> ObjCryst::RefinableObj::mClientObjRegistry [mutable, protected]

Registry of RefinableObject using this object. This is mutable so that client can modify it (kludge?)

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.

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.

bool ObjCryst::RefinableObj::mIsbeingRefined [protected]

Is the object being refined ?

CrystVector_REAL ObjCryst::RefinableObj::mLSQDeriv [mutable, protected]

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

string ObjCryst::RefinableObj::mName [protected]

Name for this RefinableObject. Should be unique, at least in the same scope.+.

long ObjCryst::RefinableObj::mNbRefParNotFixed [mutable, protected]

Total of not-fixed parameters.

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

bool ObjCryst::RefinableObj::mRandomMoveIsDone [protected]

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

RefinableObjClock ObjCryst::RefinableObj::mRefParListClock [protected]

Last time the RefinableParList was modified (a parameter added or removed).

CrystVector_long ObjCryst::RefinableObj::mRefparNotFixedIndex [mutable, protected]

Index of not-fixed parameters.

ObjRegistry<RefinableObj> ObjCryst::RefinableObj::mSubObjRegistry [protected]

Registry of RefinableObject needed for this object (owned by this object or not).

vector<RefinablePar *> ObjCryst::RefinableObj::mvpRefPar [protected]

Vector of pointers to the refinable parameters.

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.

map<unsigned long,pair<CrystVector_REAL,string> > ObjCryst::RefinableObj::mvpSavedValuesSet [mutable, protected]

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.
