double XMinimum() const

       * Return current estimate of the position of the minimum

double XLower() const

       * Return current lower bound of the minimization interval

double XUpper() const

       * Return current upper bound of the minimization interval

double FValMinimum() const

       * Return function value at current estimate of the minimum

double FValLower() const

       * Return function value at current lower bound of the minimization interval

double FValUpper() const

       * Return function value at current upper bound of the minimization interval

bool Minimize(int maxIter, double absTol, double relTol)

       * Find minimum position iterating until convergence specified by the absolute and relative tolerance or
       * the maximum number of iteration is reached
       * Return true if iterations converged successfully
       * \@param maxIter maximum number of iteration
       * \@param absTol desired absolute error in the minimum position
       * \@param absTol desired relative error in the minimum position

int Iterations() const

       * Return number of iteration used to find minimum

const char * Name() const

       * Return name of minimization algorithm

int Status() const

 Returns the status of the previous estimate
