In minisum multifacility location problems the optimal locations of clusters of facilities frequently tend to coincide. Several conditions for coincidence using attraction trees have been published recently. These conditions are extended and improved to more general location problems. Using trees of sets of facilities, a new sufficient coincidence conditions for location problems with mixed asymmetric gauges are given. Moreover, sufficient conditions are formulated, which only involve the given weights and certain values from a preprocessing step.
