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 with absolute approximation ratio smaller than $${\displaystyle {\tfrac {3}{2}}}$$ unless $${\displaystyle {\mathsf … See more The bin packing problem is an optimization problem, in which items of different sizes must be packed into a finite number of bins or containers, each of a fixed given capacity, in a way that minimizes the number of bins … See more In the online version of the bin packing problem, the items arrive one after another and the (irreversible) decision where to place an item has to be made before knowing the next item or even if there will be another one. A diverse set of offline and online … See more There are various ways to extend the bin-packing model to more general cost and load functions: • Anily, Bramel and Simchi-Levi study a setting where the … See more In the bin packing problem, the size of the bins is fixed and their number can be enlarged (but should be as small as possible). In contrast, in the See more To measure the performance of an approximation algorithm there are two approximation ratios considered in the literature. For a given list of items $${\displaystyle L}$$ the … 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 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 Webanimation of the FFD control points is produced by modeling the lattice with springs, dampers and mass points.! control points respond to gravity as well as kinematic motion …
