To ensure keep our models as transferable as possible we will keep the Bee-Distribution, minimum population size, and maximum population size the same as the tuned settings found in section 3.3.5. However, unlike the in-sphere calculations we do not need to provide a sphere radii, instead we provide an on-surface distance. In practice, we find this distance to have a negligible effect on the efficacy of the algorithm as the local optimisation tends to be the deciding factor on the the inter-molecular distance. For the purposes of our on-surface calculations the value is set to 1.2 Å.
