Unanimity games and Pareto optimality

Price of Pareto Optimality in Hedonic Games

Price of Anarchy measures the welfare loss caused by selfish behavior: it is defined as the ratio of the social welfare in a socially optimal outcome and in a worst Nash equilibrium. A similar measure can be derived for other classes of stable outcomes. In this paper, we argue that Pareto optimality can be seen as a notion of stability, and introduce the concept of Price of Pareto Optimality: t...

Pareto-optimality of Compromise Decisions Pareto-optimality of Compromise Decisions

This paper deals with the problem of existence of compromise decisions and conditions for a compromise decision to be weakly Pareto-optimal, i.e., to be a weak Pareto-maximizer, Pareto-maximizer, or strong Pareto-maximizer. The concept of compromise decision is generalized by adopting triangular norms. Further, a concept of fuzzy interval is introduced. Suucient conditions for the existence of ...

Reasoned Assumptions and Pareto Optimality

Default and non-monotonic inference rule* are not really epistemological statements, but are instead desires or preferences of the agent about the makeup of Its own mental state (cpistemic or otherwise). The fundamental relation in non-monotonic logic is not so mum self-knowledge as self-choice or self-determination, and the fundamental justification of the interpretations and structures involv...
