A set of test functions to evaluate optimization algorithms

Test Functions

Name	Definition
Beale	$f(\mathbf{x}) = (1.5 - x_1 + x_1 x_2)^2 + (2.25 - x_1 + x_1 x_$2^{2}$)^2 + (2.625 - x_1 + x_1 x_$2^{3}$)^2$
Rosenbrock	$f(\mathbf{x}) = \sum_{i = 1}^{n - 1} \{ 100 (x_{i + 1} - x_{i}^{2})^{2} + (1 - x_{i})^{2} \}$
Sphere	$f(\mathbf{x}) = \sum_{i = 1}^{n} x_{i}^{2}$
