The current approximations are based on heavy hand-made calculus by considering the specific features of the given configuration. In this paper we present a general method for characterizing all the configurations C′ which produce a given configuration C in the framework of transition P systems without cooperation and without dissolution. </style></abstract><notes><style face="normal" font="default" size="100%">Membrane Computing, 10th International Workshop, WMC 2009, Curtea de Arges, Romania, August 24-27, 2009, Revised Selected and Invited Papers.</style></notes></record></records></xml>
