A novel swarm intelligence optimization technique for constrained problems was presented. The algorithm was inspired from colonizing weeds, which is used to mimic the natural behavior of weeds in colonizing and occupying suitable places for growth and reproduction. It has the robustness, adaptation and randomness and is simple but effective with an accurate global search ability. Some applications of the new algorithm on constrained engineering design optimization via employing a penalty approach suggest that the experimental results from the proposed algorithm are promising. Also, experimental applications and comparisons show that the presented algorithm is a potential global search technique for solving complex engineering design optimization problems. Extensive simulations are conducted along with statistical tests to yield helpful conclusions regarding the effects of parameter settings on the algorithm's performance.
