Mean number of solutions found for each target set and random network pair for 50 target sets and 1,000 networks.

Custom score index and notation	1 LDOI	2 Comp_LDOI	3 Scores_1+2	4 LDOI_Pen1	5 LDOI_Pen2
Nested canalizing rules	12.29	31.66	12.30	31.21	40.64

Half of 50 target sets have size two and the other half is of size three; none of them contain source nodes. The 2nd to 6th columns correspond to different custom score (greedy function) indexes and notations, which are described in the last paragraph in section 2.7. The second and third row corresponds to the random network ensemble with nested canalizing rules and effective Boolean rules, respectively.
