“…While Sarve et al [21] employed ANN in the ultrasound-assisted transesterification using barium hydroxide as a heterogeneous catalyst, sesame oil and methanol. In order to maximize or minimize the response of an objective function, models generated using ANN are usually coupled with an optimization tool such as genetic algorithm, GA [20,22], particle swarm Sustainability 2018, 10, 707 3 of 15 optimization, PSO [23], rotation inherit optimization, RIO [24], to achieve this by optimizing the operating input variables involved.…”
