1. A method comprising: receiving a plurality of datasets, each comprising a plurality of coordinates; determining, for a coordinate of one of the plurality of datasets, analogous coordinates in each other of the plurality of datasets, the analogous coordinates defining a reduced coordinate input set; performing, by a processor, a first operation on the reduced coordinate input set to determine whether an entry is present at a coordinate of the reduced coordinate input set, wherein the first operation defines a pre-processing calculation; and automatically determining whether to perform a second operation associated with the reduced coordinate input set based on the pre-processing calculation.
