A Knowledge Module: Buying and Selling.
Joohyung Lee, Vladimir Lifschitz · 2006
This note shows how to formalize a small set of general facts about buying and selling. We begin with summarizing properties of buying/selling informally in English, and give examples of consequences of these assumptions. Then we formalize our assumptions in action language C+ with additive fluents and actions and test the adequacy of the proposed formalization using the Causal Calculator.
