NAME
    Optima - base class for optimization algorithms

SYNOPSIS
    #include <Optima.hh>

    class Optima

        \fIPublic members\fP
            Optima();
            Optima(int verb);
            virtual ~Optima();
            virtual Model<double> 	optimizer(Model<double>&) = 0;
            virtual Model<long> 	optimizer(Model<long>&) = 0;
            double		finalResidue();
            double 		firstResidue();
            List<double> 	allResidue();
            List<double> 	normResidue();
            virtual int 	numIterations();
            virtual const char* objName();
            virtual const char* optName();
            virtual Vector<double>	finalError() = 0;

        \fIProtected members\fP
            int 			iterMax;		
            double 			tol;			
            List<double>* 		residue;

DESCRIPTION
    Optima
     This is the base class for general optimization classes.
     Classes derived from this class inherit features of 
     Optima. This class cannot be used directly.
     See also NonQuaOptima, QuaOptima, LSearchOptima,
       CG, CGLS, Irls, Powell, Simplex, PreCGLS.
    

DESCRIPTION
    Saving the optimization information:
      double finalResidue(): residue of the last iteration; 
      double firstResidue(): residue of the first iteration; 
      List<double> allResidue(): residues of all iterations;
      List<double> normResidue(): normalized residues of all
         iterations;

CAVEATS
     Optima 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.
