This paper addresses the quantitative analysis of gossiping protocols. In contrast to existing approaches which are entirely based on the simulation of the individual nodes' behaviours, we present a new approach based on summary stochastic models for the peer sampling service. Instead of an ordinary state- and transition-based model, a matrix-based approach(More)
Discontinuous constituents and free word order pose constant problems in natural language parsing. String generating hyper-graph grammars have been proven useful for handling discontinuous constituents. In this paper we describe a new notation for hypergraph productions that allows on-the-fly interconnection of graph parts with regard to user-defined(More)
