Augmenting Weight Constraints with Complex Preferences
Stefania Costantini, Andrea Formisano · 2011
Abstract. Preference-based reasoning is a form of commonsense reasoning that makes many problems easier to express and sometimes more likely to have a solution. In this paper, we present an approach to introducing preferences in the weight constraint construct, which is a very useful programming construct widely adopted in Answer Set Programming (ASP). We show, mainly by means of examples, the usefulness of the proposed extension, and we outline how to accordingly extend the ASP semantics. 1
