WebDec 13, 2013 · The vector bin packing problem (VBP) is a generalization of bin packing with multiple constraints. In this problem we are required to pack items, represented by p-dimensional vectors, into as few bins as possible. The multiple-choice vector bin packing (MVBP) is a variant of the VBP in which bins have several types and items have several … WebSep 1, 2016 · In bin packing problems, items must be packed into containers or other types of boxes and spaces, generally called bins, the particular characteristics of items and bins in terms of dimensions and costs generating a rich set of problem settings and formulations (e.g., Crainic, Perboli, Rei, Tadei, 2011b, Baldi, Crainic, Perboli, Tadei, 2012 ...

The bin packing problem is an optimization problem, in which items of different sizes must be packed into a finite number of bins or containers, each of a fixed given capacity, in a way that minimizes the number of bins used. The problem has many applications, such as filling up containers, loading trucks with … See more The bin packing problem is strongly NP-complete. This can be proven by reducing the strongly NP-complete 3-partition problem to bin packing. Furthermore, there can be no approximation algorithm See more In the online version of the bin packing problem, the items arrive one after another and the (irreversible) decision where to place an item has … See more There is a variant of bin packing in which there are cardinality constraints on the bins: each bin can contain at most k items, for some fixed integer k. • Krause, Shen and Schwetman introduce this problem as a variant of optimal job scheduling: … See more In the bin packing problem, the size of the bins is fixed and their number can be enlarged (but should be as small as possible). In contrast, in the multiway number partitioning problem, the number of bins is fixed and their size … See more To measure the performance of an approximation algorithm there are two approximation ratios considered in the literature. For a given list of items $${\displaystyle L}$$ the number $${\displaystyle A(L)}$$ denotes the number of bins … See more In the offline version of bin packing, the algorithm can see all the items before starting to place them into bins. This allows to attain improved approximation ratios.
