In real-life multi-agent planning problems, long-term plans will often be invalidated by changes in the environment during or after the planning process. When this happens, short-term operational planning and scheduling methods have to be applied in order to deal with these changed situations. In addition to the dynamic environment, in such planning systems we also have to be aware of sometimes...

Most current s c hemes for multicast routing assume that multicast routers participate both in forwarding mul-ticast packets and in control algorithms for routing, resource reservation, and group management. By separating data and control ow, and by c e n tralizing control in distinct control elements, we h a ve designed a simple and scalable approach t o I P m ulticast that we call Centralized...
