Solving the qualification problem (in the presence of the frame problem)

We present a uniform nonmonotonic solution for the problem of reasoning about action on the basis of argumentation-theoretic approach in a series of paper. This paper is the first one in which we solve the frame and the qualification problems in a simplifying setting without domain constraints or ramifications. Our theory is provably correct relative to a sensible minimisation policy introduced on top of a temporal propositional logic.
