WebMar 24, 2024 · Bin-Packing Problem The problem of packing a set of items into a number of bins such that the total weight, volume, etc. does not exceed some maximum value. A … 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. See more There are various ways to extend the bin-packing model to more general cost and load functions: • Anily, Bramel and Simchi-Levi study a setting where the cost of a bin is a concave function of the number of items in the bin. The objective is to … See more
