*For each combination of algorithm, dataset and evaluation measure, 20 independent runs were performed from which averaged results are reported. By default runs were limited by a runtime of 60 seconds, except for the large pea dataset where a runtime limit of 10 minutes was applied. Furthermore the LR method does not accept a runtime limit but continues search until the desired core size has been reached.

**Results shown are those of a pseudo-index containing both minimum and mean MR distance, with equal weight = 0.5.

Not used during optimization, but computed afterwards on the constructed core sets.

Components of mixed MR measure.

These results were computed on the helios server.
