Merging Optimistic and Pessimistic Preferences

In this paper we consider the extension of non-monotonic preference logic with the distinction between controllable(or endogenous) and uncontrollable(or exogenous)variables, which can be used for example in agent decision making and deliberation. We assume that the agent is optimistic about its owncontrollables and pessimistic about its uncontrollables, and we study ways to merge these two distinct dimensions.We also consider complex preferences, such as optimistic preferences conditional on an uncontrollable, or optimistic preferences conditional on a pessimistic preference

Proceedings of the 11th Workshop on Nonmonotonic Reasoning

These are the proceedings of the 11th Nonmonotonic Reasoning Workshop. The aim of this series is to bring together active researchers in the broad area of nonmonotonic reasoning, including belief revision, reasoning about actions, planning, logic programming, argumentation, causality, probabilistic and possibilistic approaches to KR, and other related topics. As part of the program of the 11th workshop, we have assessed the status of the field and discussed issues such as: Significant recent achievements in the theory and automation of NMR; Critical short and long term goals for NMR; Emerging new research directions in NMR; Practical applications of NMR; Significance of NMR to knowledge representation and AI in general
