You have a data set that evolves, but the evolution is concentrated within specific regions of the entire data set. So, to perform a complex analysis over the entire data set is wasteful. If the algorithm could pinpoint those regions of data which require highly precise analysis, then the majority of computations could be focussed on those data regions, while less precise glosses could be applied to the data regions that are insignificantly affected.
