The identification of key players in a terrorist network can lead to prevention of attacks, due to efficient allocation … of surveillance means or isolation of key players in order to destabilize the network. In this paper we introduce a game … theoretic approach to identify key players in terrorist networks. The advantage of this approach is that both the structure of …

(2009a) introduced a quantitative approach to investigate optimal structures of covert networks. This …. Sageman (2008) hypothesized that covert networks organize according to leaderless principles, i.e., clear leaders can not be …

Extensions of these results to a class of relaxed network …This paper analyzes network problems with congestion effects from a cooperative game theoretic perspective. It is shown … that for network problems with convex congestion costs, the corresponding games have a non-empty core. If congestion costs …

This paper analyzes congestion effects on network situations from a cooperative game theoretic perspective. In network … situations players have to connect themselves to a source. Since we consider publicly available networks any group of players is … allowed to use the entire network to establish their connection. We deal with the problem of finding an optimal network, the …
