COORDINATE_SEARCH_TEST calls all the tests.

BEALE is the Beale function, for which N=2.

BOHACH1 is the Bohachevsky function #1, for which N=2.

BOHACH2 is the Bohachevsky function #2, for which N=2.

EXTENDED_ROSENBROCK is the "extended" Rosenbrock function. This version of the Rosenbrock function allows the spatial dimension N to be arbitrary, except that it must be even.

HIMMELBLAU is the Himmelblau function, for which N = 2, and which has four global minima.

LOCAL is a badly scaled function with a local minimum, for which N=2.

MCKINNON is the McKinnon function, for which N=2. This function can cause problems for the Nelder-Mead optimization algorithm.
