Choice graph for presuming cluster centers. Following the center of each group is thought, the step that is next to designate non-center services to groups.

Choice graph for presuming cluster centers. Following the center of each group is thought, the step that is next to designate non-center services to groups. Algorithm 2 defines the task of group assignment. Each solution are assigned in the region of thickness descending, which will be through the group center solutions towards the group core [...]
