Bin packing problem with two dimensions
Web3.1 Geometric Bin Packing Two-dimensional geometric bin packing (GBP) is substantially di erent from the 1-D case. Bansal et al. [BCKS06] showed that 2-D bin packing in general does not admit an APTAS unless P = NP. On the positive side, there has also been a long sequence of works giving improved approxi-mation algorithms. WebJan 14, 2024 · Introduction. The Two-Dimensional Strip Packing Problem (2SP) is composed of a given set of n rectangular items, each one with specific width w i and height h i, for i = 1, …, n, and a strip of width W and infinite height. The aim is to place all the items into the strip orthogonally; without overlapping, minimizing the overall strip’s height [1, …
