Add Red Fox Optimization (RFO) algorithm to Mealpy

[RexeneLee]

🚀 Feature Request: Red Fox Optimization (RFO)

Description

I would like to add the Red Fox Optimization (RFO) algorithm to the Mealpy library as a new swarm-based optimizer.

The implementation will follow Mealpy's existing coding standards and structure, similar to other swarm-based algorithms already included in the project.

Scope of Work

• Implement RFO as OriginalRFO under mealpy/swarm_based/RFO.py
• Follow the same design pattern used by existing swarm-based optimizers
• Add proper export in mealpy/swarm_based/__init__.py
• Include unit tests under tests/swarm_based/test_RFO.py
• Provide a simple demo script for quick testing
• Ensure all tests pass (pytest)

Reference

The algorithm will be implemented based on the original Red Fox Optimization (RFO) research paper.
(The exact paper reference will be added after verification.)

Motivation

Adding RFO will:

• Expand Mealpy’s metaheuristic algorithm collection
• Provide users with an alternative nature-inspired optimizer
• Maintain compatibility with Mealpy’s unified API

If this contribution is acceptable, I will proceed with the implementation and submit a Pull Request.

Thank you!
