In this paper we have investigated ways to incorporate both internal and external nonde-terministic actions in a system that formalizes the reasoning of agents on their abilities and the eeects of the actions that they perform. To this end we deened the notions of-nite computation sequences and nite computation runs: these are nite strings of atomic actions and tests. The results that we obtain...
