Asteroid Surface Weathering Inspired Optimization

This paper proposes a heuristic optimization algorithm based on asteroid surface weathering processes, named ASWO-I (Asteroid Surface Weathering Inspired Optimization). The algorithm simulates the physical and chemical changes on an asteroid's surface caused by solar wind bombardment, micrometeorite impacts, and spectral degradation, mapping these ...
