Eppstein (1995) gave a technique to transform any data structure for dynamic nearest neighbor queries into a data structure for dynamic closest pair, for any distance function; the transformation increases the time bound by two logarithmic factors. We present a similar, simple transformation that is just as good, and can avoid the extra logarithmic factors when the query and update time of the given structure exceedn∊for some constant∊> 0.Consequently, in the case of an arbitrary distance function, we obtain an optimalO(n)-space data structure to maintain the dynamic closest pair ofnpoints inO(n)amortized time plusO(n) distance evaluations per update.
