1. A method comprising: determining a subset of less than all of a plurality of stopover points of an initial route, wherein the plurality of stopover points are marked to indicate that an order of the plurality of stopover points is changeable; determining that at least two of the plurality of stopover points is changeable; and causing, at least in part, a calculation of a computed route in which the order is changed to minimize a metric for the computed route compared to one or more other orders of the subset.
