Batched bin packing
We introduce and study the batched bin packing problem (BBPP), a bin packing problem in which items become available for packing incrementally, one batch at a time. A batched algorithm must pack a batch before the next batch becomes known. A batch may contain several items; the special case when each batch consists of merely one item is the well-studied on-line bin packing problem. We obtain lo...
متن کاملRandom-order bin packing
An instance of the classical bin packing problem consists of a positive real C and a list L = (a1, a2, ..., an) of items with sizes 0 < s(ai) ≤ C, 1 ≤ i ≤ n; a solution to the problem is a partition of L into a minimum number of blocks, called bins, such that the sum of the sizes of the items in each bin is at most the capacity C. The capacity is just a scaling parameter; as is customary, we pu...

Best t is the best known algorithm for on line bin packing in the sense that no algorithm is known to behave better both in the worst case and in the average uniform case In practice Best t appears to perform within a few percent of optimal In this paper we study the expected performance ratio taking the worst case multiset of items L and assuming that the elements of L are inserted in random o...
متن کاملBest-Fit Bin-Packing with Random Order
Best-t is the best known algorithm for on-line bin-packing, in the sense that no algorithm is known to behave better both in the worst case (when Best-t has performance ratio 1.7) and in the average uniform case, with items drawn uniformly in the interval 0; 1] (then Best-t has expected wasted space O(n 1=2 (log n) 3=4)). In practical applications, Best-t appears to perform within a few percent...
متن کاملMore on batched bin packing
Bin packing is the problem of partitioning a set of items into subsets of total sizes at most 1. In batched bin packing, items are presented in k batches, such that the items of a batch are presented as a set, to be packed before the next batch. In the disjunctive model, a algorithm must use separate bins for the different batches. We analyze the asymptotic and absolute approximation ratios for...
