Webalgorithm and the number of bins used by a heurustic algorithm A to pack the input list L. Then, the worst-case performance ratio of A, denoted by r(A), is defined as lim L*+, supL [A(L)/L*]. This ratio is customarily used to evaluate the performance of a heuristic bin-packing algorithm.

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 $${\displaystyle {\mathsf … See more The bin packing problem is an optimization problem, in which items of different sizes must be packed into a finite number of bins or containers, each of a fixed given capacity, in a way that minimizes the number of bins … See more In the online version of the bin packing problem, the items arrive one after another and the (irreversible) decision where to place an item has to be made before knowing the next … See more There is a variant of bin packing in which there are cardinality constraints on the bins: each bin can contain at most k items, for some fixed … See more In the bin packing problem, the size of the bins is fixed and their number can be enlarged (but should be as small as possible). See more To measure the performance of an approximation algorithm there are two approximation ratios considered in the literature. For a given list of items $${\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.
