Load 7 more related questions Show fewer related questions Sorted by: Reset to The guillotine cut heuristic (see for example this paper) is imprecise but fast - when you add a box to the container then the container is split into three disjoint sub-containers, for example if you had a 12x12x12 container and added an 8x8x8 box then you would be left with a 12x12x4 container, a 12x8x4 container, and an 8x8x4 container. The goal is to efficiently pack a set of rectangles of varying dimensions into a fixed-size bin with minimal unused space. This isn't a traditional bin packing / knapsack problem where a bin has a finite capacity and you attempt to minimize the amount of bins used; I have a set amount of bins and want to use them all in order to make the Bin number 3 Items packed: [2, 7] Total weight: 61 Bin number 4 Items packed: [1] Total weight: 30 Bin number 6 Items packed: [5, 10] Total weight: 58 Bin number 8 Items packed: [3, 4] Total weight: 72 Bin number 9 Items packed: [0, 6] Total weight: 90 Bin number 10 Items packed: [8, 9] Total weight: 60 Number of bins used: 6.
