WebTo formulate the TOP, we derive a novel extension of the bin packing problem. We exploit the problem structure to decompose the TOP into two smaller, identical and independent problems. Further, we develop a mixed integer linear programming model to solve the TOP and prove that the TOP is an NP-complete problem. Webto avoid confusion. The optimization problem is NP-hard, while the problem of deciding whether a set of rectangles can be packed in a given bounding box is NP-complete, via a reduction from bin-packing (Korf, 2003). The consecutive-square benchmark is a simple set of increasingly di cult benchmarks for this problem, where the task is to nd the ...
