Presentation
Extended Spiking Neural P Systems with White Hole Rules
(Fénix Editora, 2015)We consider extended spiking neural P systems with the additional possibility of so-called \white hole rules", which send ...

Presentation
Forward and Backward Chaining with P Systems
(Fénix Editora, 2011)On the one hand, one of the concepts which lies at the basis of membrane computing is the multiset rewriting rule. On the ...

Presentation
Input-Driven Tissue P Automata
(Universidad de Sevilla, Escuela Técnica Superior de Ingeniería Informática, 2018)We introduce several variants of input-driven tissue P automata where the rules to be applied only depend on the input ...
