Gutiérrez Naranjo, Miguel ÁngelLeporati, Alberto2016-03-182016-03-1820089788461244294http://hdl.handle.net/11441/38777Recently we have considered the possibility of using spiking neural P systems for solving computationally hard problems, under the assumption that some (possibly exponentially large) pre-computed resources are given in advance. In this paper we continue this research line, and we investigate the possibility of solving numerical NP-complete problems such as Subset Sum. In particular, we first propose a semi–uniform family of spiking neural P systems in which every system solves a specified instance of Subset Sum. Then, we exploit a technique used to calculate Iterated Addition with boolean circuits to obtain a uniform family of spiking neural P systems in which every system is able to solve all the instances of Subset Sum of a fixed size. All the systems here considered are deterministic, but their size generally grows exponentially with respect to the instance size.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccess
