Approximation and online algorithms for multidimensional bin packing: A survey
Computer Science Review, 2017The bin packing problem is a well-studied problem in combinatorial optimization. In the classical bin packing problem, we are given a list of real numbers in ( 0 , 1 ] and the goal is to place them in a minimum number of bins so that no bin holds numbers

Mechanical integrity of 18650 lithium-ion battery module: Packing density and packing mode
Engineering Failure Analysis, 2018 The crash safety of lithium-ion batteries (LIBs) has recently become a hot research topic because of the wide application of LIBs in vehicle. This paper investigates how packing design of battery cells influence the energy density (volume specific) and ...

Learning practically feasible policies for online 3D bin packing
Science China Information Sciences, 2021We tackle the online 3D bin packing problem (3D-BPP), a challenging yet practically useful variant of the classical bin packing problem. In this problem, the items are delivered to the agent without informing the full sequence information. The agent must

Effect of natural and recycled aggregate packing on properties of concrete blocks
, 2021Recycled aggregate (RA) could be re-utilized in concrete paving blocks. However, the use of RA in concrete might lead to inferior performance, which constitutes a major barrier in the wider application of recycled aggregate concrete (RAC). To tackle this

Packing Arrays and Packing Designs
Designs, Codes and Cryptography, 2002For parameters for which orthogonal arrays do not exist, one may study related packing arrays. A packing array is a \(k \times b\) array with \(q\)-ary entries and with the property that in every \(t \times b\) subarray, every \(t \times 1\) column vector appears at most once. One usually wants to maximize \(b\) for given parameters.

It has been extensively recognized that the water-to-cement (w/c) ratio, solid content, and particle characteristics of tailings have substantial effects on the fluidity behaviour of cemented paste backfill (CPB). However, it is difficult to evaluate the

Mathematical Programming, 1998
A clutter (V, E) packs if the smallest number of vertices needed to intersect all the edges (i.e. a minimum transversal) is equal to the maximum number of pairwise disjoint edges (i.e. a maximum matching). This terminology is due to Seymour 1977. A clutter is minimally nonpacking if it does not pack but all its minors pack.
