Dominance testing, the problem of determining whether an outcome is preferred over another, is of fundamental importance in many applications. Hence, there is a need for algorithm...
We present a proof-technique for reducing the nondeterminbstract agent specifications in a BDI framework by means of refinement. We implement the operational semantics of agent sp...
