Multidimensional Sevilla carpets Associated with P Systems. En Cellular computing (complexity aspects): ESF PESC exploratory workshop Sevilla, January 31 - February 2, 2005 (225-236), Sevilla: Fénix Editora.84-609-5338-6https://hdl.handle.net/11441/157329In this paper we address the problem of describing the complexity of the evolution of a P system. This is especially difficult in the case of P systems where the number of membranes in creases along the computation, via division or creation of membranes. In these cases the number of steps of a computation is not sufficient to evaluate the complexity. Sevilla Carpets were introduced in [1℄, and they describe the space-time complexity of P systems. Based on them, we de ne a four-dimensional manifold whih can be used to compare evolutions of P systems.application/pdf11engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/P systemsMembrane computinginfo:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccess
