"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 … See more Denote by FF(L) the number of bins used by First-Fit, and by OPT(L) the optimal number of bins possible for the list L.
