This information is provided in the files written out by NSGA2.
- Make sure
PrintOut
is set appropriately (say 1) - The information is encoded in
nsga2_best_pop.out
but several other files are available with other information you may find useful.
Sample snippet for the example script nsga2_multi_objective.py
:
import matplotlib.pyplot as plt
import numpy as np
x = np.loadtxt("nsga2_best_pop.out")
plt.plot(x[:,0], x[:,1], '.')
plt.show()
This plots the Pareto front for this simple 2-objective problem.
