ABSTRACT
We consider the problem of packing d-dimensional cubes into the minimum number of unit cubeswith 2-space bounded, as the generalization of the classic binpacking problem. Given a sequence of items, each of whichis a d-dimensional (d ≥ 3) hypercube with side length notgreater than 1 and an infinite number ofd-dimensional (d ≥ 3) hypercube bins with unit length on each side, we want to packall items in the sequence into a minimum number of bins. The constraint is that only two bins are active at anytimeduring the packing process. Each item should be orthogonallypacked without overlapping with others. Items are given inan on-line manner which means each item comes withoutknowing any information about the subsequent items. Weextend the technique of brick partitioning in paper [1] forsquare packing and obtain two results: a three dimensionalbox partitioning scheme for cube packing and ad-dimensionalhyperbox partitioning scheme for hypercube packing. We givea 5.43-competitive algorithm for cube packing and a3221 2d-competitive algorithm for hypercube packing. To the best ofour knowledge these are the first known results on 2-spacebounded cube and hypercube packing.
