GSLSimAnFunc class description. Interface class for the objetive function to be used in simulated annealing If user wants to re-implement some of the methods (like the one defining the metric) which are used by the the simulated annealing algorithm must build a user derived class. NOTE: Derived classes must re-implement the assignment and copy constructor to call them of the parent class @ingroup MultiMin

GSLSimAnFunc(const ROOT::Math::IMultiGenFunction& func, const double* x)

construct from an interface of a multi-dimensional function

GSLSimAnFunc(const ROOT::Math::IMultiGenFunction& func, const double* x, const double* scale)

construct from an interface of a multi-dimensional function Use optionally a scale factor (for each coordinate) which can be used to scale the step sizes (this is used for example by the minimization algorithm)

GSLSimAnFunc & FastCopy(const ROOT::Math::GSLSimAnFunc& f)

fast copy method called by GSL simuated annealing internally copy only the things which have been changed must be re-implemented by derived classes if needed

GSLSimAnFunc * Clone() const

clone method. Needs to be re-implemented by the derived classes for deep copying

return new GSLSimAnFunc(const ROOT::Math::GSLSimAnFunc& )

double Energy() const

evaluate the energy ( objective function value) re-implement by derived classes if needed to be modified

void Step(const ROOT::Math::GSLRandomEngine& r, double maxstep)

change the x[i] value using a random value urndm generated between [0,1] up to a maximum value maxstep re-implement by derived classes if needed to be modified

double Distance(const ROOT::Math::GSLSimAnFunc& func) const

calculate the distance (metric) between this one and another configuration Presently a cartesian metric is used. re-implement by derived classes if needed to be modified

void Print()

print the position in the standard output std::ostream GSL prints in addition n iteration, n function calls, temperature and energy re-implement by derived classes if necessary

void SetX(unsigned int i, double x)
