Research Type Theoretical We investigate a structural way of achieving tractability, by requiring that agents preferences interact in a well-behaved manner. Precisely, we show that stable outcomes can be found in linear time for hedonic games that satisfy a notion of bounded treewidth and bounded degree. Theorem 2 (Peters 2016b). For any logical sentence φ of HG-logic that may quantify over (connected) partitions, coalitions, and agents, the problem of deciding whether a hedonic game given by an HC-net satisfies φ is fixed-parameter tractable with parameters the treewidth and degree of the dependency graph of the game. Proof idea. Encode HG-logic into monadic second-order logic, and use Courcelle s theorem.
