How to output the f_avg, f_min, cv_min, cv_avg printed when verbose=True?

[zhilei9]

After running the GA optimization with constraints, I printed the following information. Could anyone teach me how to output the f_avg, f_min, cv_min, cv_avg to a csv file.

=================================================================================
n_gen | n_eval | cv_min | cv_avg | f_avg | f_min

 1 |      100 |  0.000000E+00 |  0.2536728846 |  1.104550E+07 | -7.762836E+07

I tried the following method. However, the output values are not exactly the same as those in the above table:
optimization_info = pd.DataFrame({
'n_gen': [gen + 1 for gen in range(res.algorithm.n_gen)] [:-1],
'favg': [np.mean(-h.pop.get("F")) for h in res.history]
})
optimization_info.to_csv(config.save_path / 'optimization_info.csv', index=False)
