## Langermann Function

### Description:

*Dimensions: d*

The Langermann function is multimodal, with many unevenly distributed local minima. The recommended values of m,

**c**and

**A**, as given by Molga & Smutnicki (2005) are (for d = 2): m = 5,

**c**= (1, 2, 5, 2, 3) and:

### Input Domain:

The function is usually evaluated on the hypercube x_{i}∈ [0, 10], for all i = 1, …, d.

### Code:
