We consider a natural resource allocation problem in which we are given a set of items, where each item has a list of pairs associated with it. Each pair is a configuration of an allowed size for this item, together with a nonnegative penalty, and an item can be packed using any configuration in its list. The goal is to select a configuration for each item so that the number of unit bins needed...

In this paper, we formulate and solve an Imprecise Covering Ring Star Problem (ICRSP), which is a generalization of the (RSP). Here objective problem to find subset nodes in network minimize sum routing costs interconnecting cycle assignment are out cycle, their nearest concentrators such that no assigned node exceeds predetermined distance (say, covering distance) from concentrators. The dista...
