## Moving Peaks

The moving peaks problem have been defined as a multidimensional landscape of several peaks, where the position, height and width of each peak may change upon time. where their positions, heights and widths can be configured and depend on the time. Formally, the problem consists of **m** peaks in a **n**-dimensional real space. The fitness function is defined as the maximum among all peak functions:

where **B(x)** is a time-invariant basis landscape, and **P** is a set of functions where each moving peak is defined. Each peak **P _{i}** depends on parameters which vary across time: height (

**h**), width (

_{i}**w**) and location (

_{i}**p**).
