Genetic algorithm and particle swarm optimization combined with powell method. In 11th International Conference of Numerical Analysis and Applied Mathematics (ICNAAM).

This paper present variants of hybrid genetic algorithm - Genetic Algorithm and a bio-inspired hybrid algorithm - Particle Swarm Optimization, both combined with the local method - Powell Method. The developed methods were tested with twelve test functions from unconstrained optimization context.engGenetic algorithmGlobal optimizationLocal optimizationconference object10.1063/1.4825557
