The Michalewicz function has d! local minima, and it is multimodal. The parameter m defines the steepness of they valleys and ridges; a larger m leads to a more difficult search. The recommended value of m is m = 10. The function's two-dimensional form is shown in the plot above.
Input Domain:The function is usually evaluated on the hypercube xi ∈ [0, π], for all i = 1, …, d.
