Optimization is a key technique for maximizing or minimizing functions and achieving optimal cost, gains, energy, mass, so on. In order to solve optimization problems, metaheuristic algorithms are essential. Most of these techniques influenced by collective knowledge natural foraging. There no such thing as the best worst algorithm; instead, there more effective certain problems. Therefore, in this paper, new improved variant recently proposed metaphorless Runge-Kutta (RKO) algorithm, called...
