This is evident from the practice of using the well-known bead modeling programs. The study considers a modification of the search algorithm in a limited area of space and the behavior of the solutions depending on the parameters of the objective function responsible for the connectivity of the structure, the weight scheme for the scattering intensity curve, and the angular range of the data.
