In order to better understand this process, you will start simple with Branin function which has 3 global minima: The following code snippet shows you the minimization of the Branin function:

`import numpy as npdef branin(x):    # Branin function has 2 dimensions and it has 3 global mimima    x1 = x    x2 = x    # Global minimum is f(x*)=0.397887 at points (-pi, 12.275), (pi,2.275) and (9.42478, 2.475)    # Recommended values of a, b, c, r, s and t for Branin function    a = 1    b = 5.1 / (4 * np.pi**2)    c = 5. / np.pi    r = 6.    s = 10.    t = 1 / (8 * np.pi)    # Calculating separate parts of the function first for verbosity p1 = a * (x2 - (b * x1**2) ...`
