## Michalewicz Function

### Description:

*Dimensions: d*

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 x_{i}∈ [0, π], for all i = 1, …, d.

### Global Minima:
