从经济现实中的灵感,其中数字是基本的实体工作,我们提出了一个真正的新类型的P系统,其中数值变量的演变,从初始值开始,通过生产函数和再分配协议。我们证明了这种类型的非确定性系统,使用多项式生产函数,图灵可计算的自然数集的特征,而确定性系统,多项式生产函数具有非负系数,计算严格超过半线性自然数集。一系列的研究课题,在这个框架中提到。
With inspiration from the economic reality, where numbers are basic entities to work with, we propose a genuinely new kind of P systems, where numerical variables evolve, starting from initial values, by means of production functions and repartition protocols. We prove that non-deterministic systems of this type, using polynomial production functions, characterize the Turing computable sets of natural numbers, while deterministic systems, with polynomial production functions having non-negative coefficients, compute strictly more than semilinear sets of natural numbers. A series of research topics to be addressed in this framework are mentioned.
