Although this transformation is obtained during the computation in a P system, we consider it as a goal per se, as a pre-computation phase, when the system itself is built. In this framework, several important problems appear: the edit-distance between configurations (with respect to a given set of editing rules), normal forms, the reachability of configurations, or the existence of single configurations from which a given family of configurations can be constructed, only to mention a few. We investigate here some of these questions; the paper is mainly devoted to formulating problems in the new framework, to calling attention to the possible extensions and the usefulness of the present approach</style></abstract><issue><style face="normal" font="default" size="100%">1-2</style></issue><custom1><style face="normal" font="default" size="100%">0.715</style></custom1><custom2><style face="normal" font="default" size="100%">102/175 - Q3</style></custom2></record></records></xml>
