• Technical report TR04-12. For the Capacitated Multicast Routing Problem, we considered two models which are the Multicast k-Path Routing and the Multicast k-Tree Routing. We presented two improved approximation algorithms for them, which have worst case performance ratios of 3 and (2 + ρ) (ρ is the best approximation ratio for the Steiner Tree problem, and is about 1.55), respectively, thus improving upon the previous best ones having performance ratios of 4 and (2.4 + ρ), respectively. The designing techniques developed in the paper could be applicable to other similar networking problems. | TRID-ID TR04-12
