Complexity of comparison of influence of players in simple games

Coalitional voting games appear in different forms in multi-agent systems, social choice and threshold logic. In this paper, the complexity of comparison of influence between players in coalitional voting games is characterized. The possible representations of simple games considered are simple games represented by winning coalitions, minimal winning coalitions, weighted voting game or a multip...

Social Choice and Logic via Simple Games

ion we need, since it is clearly a property of the SAF F itself and not of any particular model based on F . This notion of validity stems from the semantics of modal logic, in which the same distinction is made between satisfaction of a formula φ as a property of models, and validity as a property of some underlying “frame”. Therefore we will look at SAFs as a variant of such modal frames. In ...
