Instead of activating Extremal Optimization, EO now has 3 modes: 0 = No EO, use Genetic Algorithm. 1 = EO Mode 1 (as before), instead of breeding clusters, clusters are just kept 2 = EO Mode 2 (new), instead of keeping clusters, they are also re-generated randomly. This means, if you use standrard herdsize of 8, Mode 0 keeps 2, breeds 3 and creates 3 new clusters per generation, Mode 1 keeps 5 and creates 3 new clustes per generation, Mode 2 Keeps 2 and creates 6 new clusters per generation.
