Algorithm 1 Chaotic maps generation pseudocode.

1. Select one of the models defined by Equations (1) through (4).

2. Define model parameters: maximum number of iteration, upper and lower boundaries,

population size, number of dimensions and the fitness function.

3. Initialize map positions randomly (i.e., $x_{\left(0\right)}$ and $y_{\left(0\right)}$).

4. Iterate n times: update $x_{n+1}$ and $y_{n+1}$

5. End iteration.
