For complex functions, it is not easy that the swarm intelligence based algorithm searchs the best optimal solution on the search area. The metaheuristic required a complex function handling approach for searching the best optimal goal only in the feasible region. In this text, we develop the search area reduction model with larger dimensionality using trigonometric functions as a newly complex functions handling algorithm. The reliability of the algorithm has been verified on benchmark and real life functions and also compared with recent metaheuristics.
