Efficiency of GB-EPI and GB-GA in the rediscovery of troglitazone, in terms of the average number of required score evaluations and CPU time in the case of a successful run, and the overall success ratio over 100 independent, randomly seeded runs of both algorithms.

Algorithm	Evaluations	CPU time	Success ratio
GB-EPI	14 258	3 min 5 s	100%
GB-GA	24 216	11 min 37 s	81%
