Actions as prolog programs

As an extention of the TRASYS approach to reasoning about actions, this work presents a new step in the direction to the transposition of the gap between action formalisms and their real execution inside planning environments. We try to clarify some points of the former paper by presenting a re-structured overview ofthe Transaction Logic formalism and proposing some modifications to the action model which will allow the use of non-atomic formulae in the world model. Aiming an efficient method for executing action specifications, we present how could these specifications be rendered into a PROLOG program.
