Strip packing problem
WebMar 1, 2024 · As a typical NP-hard combinatorial optimization problem, the main objective of the rectangular 2D strip packing problem (2D-SPP) is to pack a set of small rectangles into one strip with a fixed width and virtually infinite height, minimizing the required height. WebAbstract. In this study, we propose a new algorithm to solve the rectangular strip packing problem (RSPP), a variant of the cutting stock problem in which the mother materials have a common fixed width and infinite length. Based on the column-generation technique with three improvements, the proposed algorithm can solve large-scale problems ...
