/**
 *  File name: CRealProblem.h
 *
 *  Programmer: Yongqun He
 *  Contact email: yohe@vt.edu
 *  Purpose: This is the header file of the CRealProblem class.
 *           It specifies the optimization problem with its own members and
 *           functions. It's used by COptAlgorithm class and COptimization class
 *           It's a subclass of COptProblem
 *
 *  The specific purpose here is to use it to demonstrate that the system works
 *  fine. It is for my independent study project.  -- Yongqun He
 *
 *  The function I use here is a N-Dimensional Test Function:
 *            f(x) = (1/2)Sum(j=1, n)(Xj^4 - 16Xj^2 + 5Xj)
 *        where, x = [X1, X2, ... , Xj, ..., Xn]
 *        Number of global minima = 1;
 *    Global minimum found by TRUST is:
 *        [-2.90354, -2.90354, ..., -2.90354].
 *
