Abstract. We present a scalable and flexible grouping service based on concast and best-effort single-source multicast. The service assigns participating end systems to specific gr...
Reconfiguration means changing the set of processes executing a distributed system. We explain several methods for reconfiguring a system implemented using the state-machine appro...
Unsupervised learning algorithms aim to discover the structure hidden in the data, and to learn representations that are more suitable as input to a supervised machine than the ra...
We show that the reachability problem for recursive state machines (or equivalently, pushdown systems), believed for long to have cubic worst-case complexity, can be solved in sli...
Multicriteria analysis can be incorporated as a method to model preferences and facilitate decision making within a group of decision makers. In this paper we present a Group Deci...
