Abstract
Consider a parameter α>0, and a large integer AT. Assume that for P≥1, we are given a family I p of [2-αp N] random intervals of [0,1], and consider the union I of the families Ip . A packing of I is a disjoint sub family of I. The cost of the packing is the sum of the wasted space (the measure of the part of [0,1] not covered by the packing) and the costs of the intervals of the packing, where, if l∊ Ip , the cost of I is 2-p |I|. We estimate as a function of N, the expected value of the cost of an optimal packing. We discover the very surprising fact that (up to terms of smaller order) this cost behaves as N -1/2 for all 1≤α≤2. This problem is motivated by a problem of packing random rectangles.
