In Table 3, we present the results from evaluating the nine algorithms with three datasets in case of no constraints. We use the scheme W2 : wr = wu = wp = wh = 1 and wd = ∞. The scheme W2 assumes that the cost of adding each element (a role or a relationship) to the RBAC state is 1 while direct user permission assignments are not allowed. The weighted structural complexity thus measures the cost to create the RBAC state. We can see that CRM has smaller WSC than other algorithms on average.
