The following input data should be provided to run DISCRETE GRADIENT
METHOD (for unconstrained minimization).

A. In main Program:

       1. n  - number of variables\par

       2. nbundle - the maximum number of discrete gradients which can be calculated at each iteration
       
       4. Starting point: x0

B. In Subroutine FUNC the objective function is described

The rest of the source code should not be changed.

The code generates one output file: RESULTS.TXT. It contains the following information:
    1. The value of the objective function at the starting point;
    2. The value of the objective function at the solution;
    3. The number of the objective function evaluations;
    4. CPU time
