In the present paper, we consider the asynchronous parallelism in membrane computing, and propose fully asynchronous P systems such that any number of applicable rules may be applied in one step. Since there is no restrictive assumption for application of rules, sequential and maximal parallel executions are allowed on the asynchronous P system. We propose two asynchronous P systems for the satisfiability...
In the present paper, we propose P systems that work in a constant number of steps. We first propose two P systems for computing multiple input logic functions. An input of the logic functions is a set of n binary numbers of m bits, and an output is a binary number defined by the logic functions. The first and second P systems compute AND and EX-OR functions for the input, and both of the P systems...
