multiple spawns from one configuration to another (a "bloom" event) cause the calculation to become unstable. In order to reduce inefficiencies, new configurations |D j should not be suggested uniformly in the excitation generation step. Instead, they should be selected with a probability p gen ∝ D i | Ĥ | D j , such that important connections are sampled more often and the spawn probability p spawn ∝ ∆τ
