NAME
    ObjFcn

SYNOPSIS
    #include <ObjFcn.hh>

    class ObjectiveFunction

        \fIPublic members\fP
            ObjectiveFunction(int n);
            virtual ~ObjectiveFunction();
            virtual const char* className() const;
            double performance(Model<long>& p);
            double performance(Model<double>& p);
            int	iterations();
            virtual Vector<double>* getGradient(Model<double>&);
            virtual Vector<double>* getGradient(Model<long>&);

        \fIProtected members\fP
            int	nparam;
            int	niteration;
            Vector<double>* gradient;
            virtual double realPerformance(Model<long>& p)  = 0 ;
            virtual double realPerformance(Model<double>& p) = 0;

DESCRIPTION
    ObjectiveFunction
     This is the base class for general objective functions 
     for optimizations. Classes derived from this class inherit
     features of ObjectiveFunction.
     This class cannot be used directly.
     See also DirectObjFcn, MisFit, RosenBrock, MultiTest, Quadr.
    

CAVEATS
     ObjectiveFunction currently only takes Models either double 
     or long integer. It is mostly because I tried to avoid using
     templates, due to the guliness of template features in G++. 
     Hopefully, this could be changed soon.
