Minion : a high-performance derivative-free optimization library designed for solving complex optimization problems.

Minion is a high-performance derivative-free optimization library designed for solving complex optimization problems where gradients are unavailable or unreliable. It implements state-of-the-art evolutionary algorithms, including top-performing methods from IEEE CEC competitions, which are often missing in standard optimization libraries such as SciPy, NLopt, OptimLib, pyGMO, and pagmo2.

Minion is not only a solver but also a research platform for developing and testing new optimization algorithms. It includes benchmark functions from CEC competitions (2011, 2014, 2017, 2019, 2020, and 2022), providing a robust framework for algorithm evaluation and comparison.

Features:

• State-of-the-art optimization algorithms: Implements JADE, L-SHADE, jSO, j2020, NL-SHADE-RSP, LSRTDE, and ARRDE (our novel Adaptive Restart-Refine DE algorithm).
• Parallelization-ready: Supports vectorized function evaluations, allowing seamless integration with multithreading and multiprocessing for high-performance optimization.
• Optimized C++ backend with a Python wrapper: Provides high efficiency with an easy-to-use Python API.
• CEC Benchmark Suite: Includes benchmark problems from 2011, 2014, 2017, 2019, 2020, and 2022 for rigorous testing and comparison.

MinionPy: Python Package

Minion is available as a Python package called MinionPy, which provides an easy-to-use interface for Python users while benefitting from the optimized C++ backend. It can be installed via pip:

pip install minionpy

This package allows users to access Minion’s optimization algorithms directly in Python, making it suitable for both research and practical applications.
