Abstract

A set of items has to be assigned to a set of bins with size one. If necessary, the size of the bins can be extended. The objective is to minimize the total size, ie., the sum of the sizes of the bins. The Longest Processing Time-neuristic is applied to this NP-hard problem. For this approximation algorithm we prove a worst-case bound of 13/12 which is shown to be tight when the number of bins is even.
