網頁1992年10月20日 · Description. The Steiner problem asks for a shortest network which spans a given set of points. Minimum spanning networks have been well-studied when all connections are required to be between … 網頁The Steiner problem on networks asks for a shortest subgraph spanning a given subset of distinguished vertices. We give a 4 3 -approximation algorithm for the special case in which the underlying network is complete and all edge lengths are either 1 or 2. We also relate the Steiner problem to a complexity class recently defined by Papadimitriou and Yannakakis …
