WebHere we consider the classical Bin Packing problem: We are given a set I = {1,...,n }of items , where item i ∈I has size s i ∈(0 ,1] and a set B = {1,...,n }of bins with capacity one. Find an assignment a : I →B such that the number of non-empty bins is minimal. ... items with sizes less than ε into the solution found for instance I ... WebIn most real-world applications of bin packing, as in Theorem 1, the item sizes are drawn from some nite set. However, the usual average-case analysis of bin packing heuristics has assumed that item sizes are chosen according to continuous probability distributions, which by their nature allow an uncountable number of possible item

Webdenote the sum of the item sizes in L (an obvious lower bound on the optimal number of bins, since the bin size is 1). Then we have the following contrasting results: Theorem 2. For all u < 1, ifL. is an n-item list with item sizes drawn independently from U(O, u] and A is any on-line bin packing algorithm, then EIA(Lfl) – s(L. )] = i2(n1’2 ...
