Coalition governance in South Africa is adjudged as an opportunity for nation-building and social compact, which intends to jettison the apartheid legacy of racial separation. quintessentially demonstrates a maturing project whereby political parties embrace cohesive spirit democratic citizenship representation. However, lack consensus about developmental posture drive put different on antithet...

Funded by the Swiss National Science Foundation to promote cutting edge research as well as the advancement of young researchers and women, technology transfer, outreach and education, the NCCR (Swiss National Centre of Competence in Research) Chemical Biology is co-led by Howard Riezman, University of Geneva and Kai Johnsson, École Polytechnique Fédérale de Lausanne (EPFL).

A coalitional (or cooperative) game is a model of interacting decision-makers that focuses on the behavior of groups of players. N denotes the set of players. A coalition is a group of players S ⊂ N . We refer to N as the grand coalition. Every coalition S has a set of available actions AS. An outcome consists of a partition of N (coalition structure) and one action associated with each coaliti...

A value for games with a coalition structure is introduced, where the rules guiding cooperation among the members of the same coalition are different from the interaction rules among coalitions. In particular, players inside a coalition exhibit a greater degree of solidarity than they are willing to use with players outside their coalition. The Shapley value is therefore used to compute the agg...

The existence of a coalition strategy to achieve a goal does not necessarily mean that the coalition has enough information to know how to follow the strategy. Neither does it mean that the coalition knows that such a strategy exists. The paper studies an interplay between the distributed knowledge, coalition strategies, and coalition “know-how” strategies. The main technical result is a sound ...

We study the myopic stability of hedonic coalition formation. Myopic stability means that for each unstable coalition structure there exists a sequence of myopic blockings that leads to a stable coalition structure. The main result is a characterization of the hedonic coalition formation models which are myopically stable whenever a stable coalition structure exists. One interesting implication...

We add a limited but useful form of quantification to Coalition Logic, a popular formalism for reasoning about cooperation in game-like multi-agent systems. The basic constructs of Quantified Coalition Logic (QCL) allow us to express such properties as “every coalition satisfying property P can achieve φ” and “there exists a coalition C satisfying property P such that C can achieve φ”. We give ...
