Simple Games versus Weighted Voting Games: Bounding the Critical Threshold Value

Frits Hof, Walter Kern, Sascha Kurz +2

A simple game is given by a set of players and a partition of~ into a set~ of losing coalitions~ with value that is closed under takin…

Computing the Nucleolus of Weighted Voting Games in Pseudo-polynomial Time

Kanstantsin Pashkovich

We provide an algorithm for computing the nucleolus for an instance of a weighted voting game in pseudo-polynomial time. This resolves an open question posed by Elkind. et.al. 2007…

On the approximability of the stable matching problem with ties of size two

Robert Chiang, Kanstantsin Pashkovich

The stable matching problem is one of the central problems of algorithmic game theory. If participants are allowed to have ties, the problem of finding a stable matching of maximum…

Three-dimensional Stable Matching with Cyclic Preferences

Kanstantsin Pashkovich, Laurent Poirrier

We consider the three-dimensional stable matching problem with cyclic preferences, a problem originally proposed by Knuth. Despite extensive study of the problem by experts from di…

On Critical Threshold Value for Simple Games

Kanstantsin Pashkovich

In this note, we show that for every simple game with n players the critical threshold value is at most n/4. This verifies the conjecture of Freixas and Kurz.

Computing the Nucleolus of Weighted Cooperative Matching Games in Polynomial Time

Jochen Koenemann, Kanstantsin Pashkovich, Justin Toth

We provide an efficient algorithm for computing the nucleolus for an instance of a weighted cooperative matching game. This resolves a long-standing open question posed in [Faigle,…
