test_optimization, a MATLAB code 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;
