Abstract: In this paper we address the problem of describing the complexity of the evolution of a P system. This issue is is specially hard in the case of P systems with active membranes, where 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 define some new parameters which can be used to compare evolutions of P systems. To illustrate this, we also include two different cellular solutions to the Subset Sum problem and compare them via these new parameters.
