First-fit (FF) is an online 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. The first-fit algorithm uses the following heuristic: WebNov 12, 2014 · FF performs as follows: The items are first given in some list L and then are handled by the algorithm in this given order. Then, algorithm FF packs each item into the first bin where it fits; in case the item does not fit into any already opened bin, the algorithm opens a new bin and puts the actual item there.
