1. A system for selecting optimal stimulation parameter settings for a current patient, comprising: at least one computer processor configured to: obtain a plurality of electrical parameter maps and corresponding score values from a plurality of patients including the current patient, each electrical parameter map corresponding to a one of the plurality of patients and representing different sets of one or more electrical stimulation parameters, wherein each of the score values is associated with one of the different sets of one or more electrical stimulation parameters and represents a behavior of the patient upon electrical stimulation using that set of one or more electrical stimulation parameters; and process the electrical parameter maps and the score values to evaluate, based on a set of score criteria, potential parameter maps, including a potential parameter map that is different than all of the plurality of electrical parameter maps, associated with respective potential stimulation parameter settings.
