Abstract
The work described in this report is motivated by the desire to test the expressive possibilities of
action language C+. The Causal Calculator (CCALC) is a system that answers queries about action
domains described in a fragment of that language. The Zoo World and the Traffic World have been
proposed by Erik Sandewall in his Logic Modelling Workshop—an environment for communicating
axiomatizations of action domains of nontrivial size.
The Zoo World consists of several cages and the exterior, gates between them, and animals of
several species, including humans. Actions in this domain include moving within and between cages,
opening and closing gates, and mounting and riding animals. The Traffic World includes vehicles
moving continuously between road crossings subject to a number of restrictions, such as speed
limits and keeping a fixed safety distance away from other vehicles on the road. We show how to
represent the two domains in the input language of CCALC, and how to use CCALC to test these
representations.(C)2003 Elsevier B.V. All rights reserved.
