Networks of splicing processors: simulations between topologies
Journal of Membrane Computing - Tập 5 - Trang 108-115 - 2023
Networks of splicing processors are one of the theoretical computational models that take inspiration from nature to efficiently solve problems that our current computational knowledge is not able to. One of the issues restricting/hindering is practical implementation is the arbitrariness of the underlying graph, since our computational systems usually conform to a predefined topology. We propose ......
When catalytic P systems with one catalyst can be computationally complete
Journal of Membrane Computing - Tập 3 - Trang 170-181 - 2021
Catalytic P systems are among the first variants of membrane systems ever considered in this area. This variant of systems also features some prominent computational complexity questions, and in particular the problem of using only one catalyst in the whole system: is one catalyst enough to allow for generating all recursively enumerable sets of multisets? Several additional ingredients have been ......
Universality of spiking neural P systems with polarizations working in sequential mode induced by maximum spike number
Journal of Membrane Computing - Tập 4 - Trang 56-67 - 2021
Based on the inspiration that the communication signal between neurons in biology is composed of short electrical pulses, we investigate a new variant of spiking neural P systems, i.e., spiking neural P systems with polarizations (PSN P systems), which have a rule-triggering condition associated with polarization. In this work, we focus on the computational power of sequential PSN P systems with d......
P-Lingua in two steps: flexibility and efficiency
Journal of Membrane Computing - Tập 1 - Trang 93-102 - 2019
Membrane computing is a bio-inspired computing paradigm that lacks in vivo implementation. That is why software or hardware implementations have to be used to validate models. Several tools have been created for this purpose; some of them are created for specific purposes, such as solving a computationally hard problem; and others are more generic, to cover a broad spectrum of possible models. The......
Implementation of RSA cryptographic algorithm using SN P systems based on HP/LP neurons
Journal of Membrane Computing - Tập 3 - Trang 22-34 - 2021
Asymmetric cryptographic systems are often more complex and require more computational power than symmetric systems. This is why they might be implemented using unconventional computing systems, such as P systems, spiking neural systems, and DNA computing. In this work, we design an implementation model for RSA encryption and decryption algorithms in the framework of Spiking neural P systems with ......
Multi-learning rate optimization spiking neural P systems for solving the discrete optimization problems
Journal of Membrane Computing - Tập 4 - Trang 209-221 - 2022
To further improve the performance of optimization spiking neural P system (OSNPS), a multi-learning rate optimization spiking neural P system (MLOSNPS) is proposed. More specifically, by borrowing the distributed population structure of DAOSNPS, the distributed population structure with multiple subpopulations, single migration individual and information exchange considering convergence and diver......
Turing completeness of water computing
Journal of Membrane Computing - Tập 3 - Trang 182-193 - 2021
We further develop water computing as a variant of P systems. We propose an improved modular design, which duplicates the main water flows by associated control flows. We first solve the three open problems of the previous design by demonstrating: how functions can be stacked without a combinatorial explosion of valves; how termination of the system can be detected; and how to reset the system. We......

Extracting reaction systems from function behavior
Journal of Membrane Computing - Tập 2 - Trang 194-206 - 2020
Reaction systems, introduced by Ehrenfeucht and Rozenberg, are a theoretical model of computation based on the two main features of biochemical reactions: facilitation and inhibition, which are captured by the individual reactions of the system. All reactions, acting together, determine the global behavior or the result function, res, of the system. In this paper, we study decomposing of a given r......
