“…The attempts are also made by researchers to maximize the production rate (or minimize machining time) using genetic algorithm (Aggarwal & Xirouchakis, 2012), simulated annealing (Rao & Pawar, 2010), artificial bee colony (Rao & Pawar, 2010), particle swarm optimization (Rao & Pawar, 2010;Gao et al, 2012), harmony search algorithm (Zarei et al, 2009), cuckoo search algorithm (Yildiz, 2012), and teaching learning based optimization algorithm (Pawar & Rao, 2013). Considering cutting force as an objective, researchers employed particle swarm optimization (Farahnakian et al, 2011), for optimization of milling process parameters. Multiobjective optimization for milling process is attempted by researchers using posteriori approaches namely non-dominated sorting genetic algorithm (NSGA) (Wang et al, 2006) and multi-objective particle swarm optimization (MPSO) (Yang et al, 2011).…”
