First-fit-decreasing (FFD) is an algorithm for bin packing. Its input is a list of items of different sizes. 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.
In the optimal packing, the weight of each bin is at most 17/12; In the First-Fit packing, the average weight of each bin is at least 5/6 = 10/12. Therefore, asymptotically, the number of bins in the FF packing must be at most 17/10 * OPT. For claim 1, it is sufficient to prove that, for any set B with sum at most 1, bonus(B) is at most 5/12 ...
What a waste, I think to myself every time I open a package and and a geyser of foam packing peanuts erupts. A waste of money, a waste of my time spent cleaning up the detritus, and a waste of ...
Bin-packing with fragmentation or fragmentable object bin-packing is a variant of the bin packing problem in which it is allowed to break items into parts and put each part separately on a different bin. Breaking items into parts may allow for improving the overall performance, for example, minimizing the number of total bin.
Best-fit 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 ...
The law also requires more recycled plastic, glass and paper to be used in everyday products.
