## Properties vs. Resources: Solving Simple Frame Problems

### Steffen Hölldobler and Michael Thielscher

Most solutions to the technical frame problem in theories of a
ctions depend
on special axioms like the frame axioms, the law of inertia, or the
successor state axioms. In these solutions facts about a situation are
regarded and represented as properties which hold in the situation. In this
article it is argued that it is often more adequate to view facts about a
situation as resources which are available in the situation. As resources
can be consumed and produced a representation of the facts about a situation
as resources leads to a solution of the technical frame problem without the
need to state any additional axioms.

In order to substantiate our claim we present a simple problem class
such that the complexity of a method based on the situation calculus
is quadratic regarding this class, whereas it has a linear
solution in a resource-oriented approach.
