Modified first fit decreasing (MFFD) [9] improves on FFD for items larger than half a bin by classifying items by size into four size classes large, medium, small, and tiny, corresponding to items with size > 1/2 bin, > 1/3 bin, > 1/6 bin, and smaller items respectively. Then it proceeds through five phases:
Therefore, Next-Fit-Increasing has the same performance as Next-Fit-Decreasing. [26] Modified first-fit-decreasing (MFFD) [27], improves on FFD for items larger than half a bin by classifying items by size into four size classes large, medium, small, and tiny, corresponding to items with size > 1/2 bin, > 1/3 bin, > 1/6 bin, and smaller items ...
First-Fit-Decreasing (FFD) is the offline variant of First-Fit: it accepts all input items, orders them by descending size, and calls First-Fit. Its asymptotic approximation ratio is much better: about 1.222 instead of 1.7.
Continue packing the items using the First-Fit heuristic. Each following level (starting at level three) is defined by a horizontal line through the top of the largest item on the previous level. Note that the first item placed in the next level might not touch the border of the strip with their left side, but an item from the first level or ...
