For the trajectory optimization of time–jerk robotic arms with a chicken swarm algorithm, using five-order B-spline interpolation can ensure smooth and continuous acceleration, but, due to performance problems low solution accuracy slow convergence speed, ideal curve cannot be obtained. To address these problems, an improved algorithm based on parallel strategy dynamic constraints (PDCSO) is pr...
