A NOVEL GRAPH BASED ALGORITHM FOR ONE DIMENSIONAL BIN PACKING PROBLEM

First-fit-decreasing (FFD) is an algorithm for bin packing. Its input is a list of items of different sizes. Its output is a packing - a partition of the items into bins of fixed capacity, such that the sum of sizes of items in each bin is at most the capacity. Ideally, we would like to use as few bins as possible, but minimizing the number of bins is an NP-hard problem, so we use an approximately-optimal heuristic. WebDec 11, 2024 · FFD: Fast Feature Detector. Abstract: Scale-invariance, good localization and robustness to noise and distortions are the main properties that a local feature … The bin packing problem is strongly NP-complete. This can be proven by reducing the strongly NP-complete 3-partition problem to bin packing. Furthermore, there can be no approximation algorithm with absolute approximation ratio smaller than $${\displaystyle {\tfrac {3}{2}}}$$ unless $${\displaystyle {\mathsf … See more The bin packing problem is an optimization problem, in which items of different sizes must be packed into a finite number of bins or containers, each of a fixed given capacity, in a way that minimizes the number of bins … See more In the online version of the bin packing problem, the items arrive one after another and the (irreversible) decision where to place an item has to be made before knowing the next item or even if there will be another one.
