Considerate Equilibrium
Martin Hoefer, Michal Penn, Maria Polukarov +2
We consider the existence and computational complexity of coalitional stability concepts based on social networks. Our concepts represent a natural and rich combinatorial generaliz…
Approximation Algorithms for Secondary Spectrum Auctions
Martin Hoefer, Thomas Kesselheim, Berthold Vöcking
We study combinatorial auctions for the secondary spectrum market. In this market, short-term licenses shall be given to wireless nodes for communication in their local neighborhoo…
Contribution Games in Social Networks
Elliot Anshelevich, Martin Hoefer
We consider network contribution games, where each agent in a social network has a budget of effort that he can contribute to different collaborative projects or relationships. Dep…
Strategic Cooperation in Cost Sharing Games
Martin Hoefer
In this paper we consider strategic cost sharing games with so-called arbitrary sharing based on various combinatorial optimization problems, such as vertex and set cover, facility…
