標題: | The Steiner Problem in Distributed Computing Systems | 作者: | 陳健輝 Houle, M. E. Kuo, M. T. |

The worst-case cost ratio of the obtained solution to any given minimum-cost Steiner tree Tmin is 2( 1-1 l), where l is the number of leaves of Tmin. The message complexity of the algorithm is O(|E| + |V|*(|V| + log|V|)) and the time complexity is O|V|*|V|), where S is the subset of nodes of G to be connected. © 1993. |
