TEST_OPTIMIZATION
Test Functions for Optimization

TEST_OPTIMIZATION is a FORTRAN90 library which defines test problems for the scalar function optimization problem.

The scalar function optimization problem is to find a value for the M-dimensional vector X which minimizes the value of the given scalar function F(X).

A special feature of this library is that all the functions can be defined for any dimension 1 <= M.

The functions defined include:

1. The sphere model;
2. The axis-parallel hyper-ellipsoid function;
3. The rotated hyper-ellipsoid function;
4. Rosenbrock's valley;
5. Rastrigin's function;
6. Schwefel's function;
7. Griewank's function;
8. The power sum function;
9. Ackley's function;
10. Michalewicz's function;
11. The drop wave function;
12. The deceptive function;
