摘要：By considering string-objects and rewriting rules, we propose a variant of tissue P systems, namely, rewriting tissue P systems. We show the computational efficiency of rewriting tissue P systems by solving the Satisfiability and the Hamiltonian path problems in linear time. We study the computational capacity of rewriting tissue P systems and show that rewriting tissue P systems with at most two cells and four states are computationally universal. We also show the universality result of rewriting tissue P systems with at most one cell and five states. Finally we propose some new directions for future work.
