“…Variety of nature-inspired algorithms are there, such as genetic algorithm (GA) [17,18], particle swarm optimization (PSO) [19], teaching learning-based algorithm (TLBO) [20], whale optimization algorithm (WOA) [21] and many more, to solve the objective function which is a Euclidean distance [22] in our case that is selected path. Improved algorithms such as modified particle search algorithm (MPSO) [23] and hybrid teaching learning-based algorithm [24] are proposed for more refinement in the solution of the design variables. Thus, in this paper, an optimal fourbar crank-rocker mechanism is proposed for agricultural tillage operation for the desired path.…”
