β¦ Synopsis
We use the notion of domination ratio introduced by Glover and Punnen in 1997 to present a new classiΓΏcation of combinatorial optimization (CO) problems: DOM-easy and DOM-hard problems. It follows from results already proved in the 1970s that min TSP (both symmetric and asymmetric versions) is DOM-easy. We prove that several CO problems are DOM-easy including weighted max k-SAT and max cut. We show that some other problems, such as max clique and min vertex cover, are DOM-hard unless P = NP.

We characterize (0,l) linear programming matrices for which a greedy algorithm and its dual solve certain covering and packing problems. Special cases are shortest path and minimum spanning tree algorithms.
This paper presents some results regarding the design of reliable networks. The problem under consideration involves networks which are undirected graphs having equal and independent edge failure probabilities. The index of reliability is the probability that the network fails (becomes disconnected)
