Abstract

Tissue P systems with channel states are a variant of tissue P systems that can be employed as highly parallel computing devices, where the channel states can control the movements of objects. In a sense, the time-free approach can improve the robustness of P systems; hence, in this work, we introduce the time-free property into such P systems and explore their computational performances. Specifically, in a time-free manner, it is proved that this type of P systems have Turing universality by using two cells and four channel states with a maximum rule length of 2, or by using two cells and noncooperative symport rules with a maximum rule length of 1. Moreover, in terms of computational efficiency, it is proved that a uniform solution of the satisfiability ( $\mathcal {SAT}$ ) problem can be obtained in a time-free manner by applying noncooperative symport rules with a maximum rule length of 1. The research results of this paper show that a highly robust dynamic membrane computing system is constructed. Theoretically, relative to the existing system, our constructed system can enhance robustness and expand its application scope.
具有通道状态的定时组织 P 系统
具有通道状态的组织 P 系统是组织 P 系统的一种变体,可用作高度并行计算设备,其中通道状态可控制物体的运动。从某种意义上说,无时间方法可以提高 P 系统的鲁棒性;因此,在这项工作中,我们将无时间特性引入此类 P 系统,并探索其计算性能。具体来说,在无时间方式下,通过使用最大规则长度为 2 的两个单元和四个通道状态,或使用最大规则长度为 1 的两个单元和非合作交配规则,证明了这类 P 系统具有图灵普遍性。此外,在计算效率方面,本文证明了通过应用最大规则长度为 1 的非合作交配规则,可以在无时间限制的情况下获得可满足性(SAT)问题的统一解。从理论上讲,相对于现有系统,我们构建的系统可以增强鲁棒性并扩大其应用范围。
