A new hybrid Harris hawks optimization (HHO) and particle swarm optimization (PSO) algorithm for the design of castellated beams

In this paper, a hybrid meta-heuristic algorithm based on Harris Hawk Optimization (HHO) and Particle Swarm (PSO) is developed used to design castellated beams. The total cost, including material construction costs, taken as the objective function, code requirements geometry limitations have been considered in constraint functions. proposed method obtain optimal solution of three examples. then compared with results five known methods. It observed that achieves better higher convergence speed
