Example

The 'Golden' method minimizes a unimodal function by narrowing the range in the extreme values

import numpy as np
from scipy.optimize import _minimize
from scipy import special
import matplotlib.pyplot as plt

x = np.linspace(0, 10, 500)
y = special.j0(x)
optimize.minimize_scalar(special.j0, method='golden')
plt.plot(x, y)
plt.show()
