We add to such systems the basic feature of (cell) P systems with active membranes { the possibility to divide cells. As expected (as it is the case for P systems with active membranes), in this way we get the possibility to solve computa- tionally hard problems in polynomial time; we illustrate this possibility with SAT problem.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccesshttps://idus.us.es/xmlui/handle/11441/36476
