Abstract
Nowadays the root finding problem for nonlinear system equations is still one of the difficult problems in computational sciences. Many attempts using deterministic and meta-heuristic methods have been done with their advantages and disadvantages, but many of them have fail to converge to all possible roots.Differential Evolution (DE), a random search techniques using vector as an alternative solution in the search for finding all ofthe real roots from the system of nonlinear equations. Species-based is one of the methods niching the building sub-populations or species in the area with species-seed functions as its center. This study will describe the modification of existing species-based previously to reduce the computational complexity and run more efficiently. The results of the test function shows species-based modifications can localize all potential roots with one running the program
