There are various ways to extend the bin-packing model to more general cost and load functions: • Anily, Bramel and Simchi-Levi study a setting where the cost of a bin is a concave function of the number of items in the bin. The objective is to minimize the total cost rather than the number of bins. They show that next-fit-increasing bin packing attains an absolute worst-case approximation ratio of at most 7/4, and an asymptotic worst-case ratio 1.691 for any concave and monotone co… WebMay 28, 2024 · Consider the following problem, Non-Uniform Bin Packing: the input is a list of bin sizes and item sizes and we want to know if we can put all the items in the bins …
