See more at minimum Examples of global minimumglobal minimum Regarding the convergence of the distributed gradient algorithm to the globalminimum this can be sure only in the case of a convex cost function. Due to the probabilistic increase, the energy tends to reach the globalminimum by escaping from local minima. The course of the trajectory is unimportant, as long as its end point comes close to the globalminimum of the target function. Beyond that, there is always hope of finding a better solution among the other local minima, and maybe the globalminimum. The danger map towards the target is thus also a convex map, with the target as the single globalminimum. Secondly, most optimization problems depend on the initial guesses, and identification of the globalminimum is not guaranteed. The globalminimum of the target function, or a close enough approximation of it, is sought, whereas local minima are to be avoided. For the path planning problem, the goal configuration must be designed as the unique globalminimum of the configuration variables. The lateral separation of the trajectories is less than one percent of the distance between the globalminimum and maximum of the trajectories. The purpose with using forgetting factor is to help the algorithm converge to the globalminimum. In particular, it is quite possible for such a method to miss the globalminimum. There is no theoretical work on conditions that would ensure convergence to the globalminimum. It remains open to prove that the solution corresponds to a globalminimum. So, we cannot assure that a globalminimum has been reached. This means that if the robot is disturbed from a stagnation point, it will continue its way toward the globalminimum of the potential.
