Nakanishi-Fujii-Todo method for scipy.optimize

This is Nakanishi-Fujii-Todo method (arXiv:1903.12166) for scipy.optimize.minimize.

The optimization function have to satisfy three conditions written in [1].

install

pip install nftopt

or

pip3 install nftopt

Example code

from scipy.optimize import minimize
from nftopt import nakanishi_fujii_todo


res = minimize(
    YOUR_FUNC,
    YOUR_PARAM,
    options={'maxfev': 2048},
    method=nakanishi_fujii_todo,
    callback=YOUR_EVAL_FUNC
)
