The constrained modification is solved in 2d and in 3d to determine whether a solution exists in which all constraints are met. If the solve is successful, the constrained modification is applied to each dataset simultaneously and, updated datasets are stored. If the solve fails, the constraints may be reduced and the solve step repeated, or the process is terminated.
