To this end, we define two possible measures, the first one to reflect the entropy of the P system considered as the state space of possible computations, and the second one to reflect the change of the P system as it evolves. }, keywords = {Entropy, Natural computing, P systems}, url = {http://www.jucs.org/jucs_10_5/a_note_on_complexity}, attachments = {http://www.gcn.us.es/files/A note on Complexity Measures....pdf}, author = {Andr{\'e}s Cord{\'o}n-Franco and Fernando Sancho-Caparrini} }
