在给出模糊树自动机概念的基础上,讨论了模糊树自动机与传统字符自动机、模糊有限自动机相类似的性质,即指确定性模糊树自动机与非确定性的模糊树自动机的等价性、FNBTA与FNTTA等价,及FDBTA和FNBTA等价;这为模糊树自动机的进一步研究奠定了基础.
In this paper, the concept of fuzzy tree automaton is defined. Then some properties of fuzzy tree automata which are similar to those of tranditional automata or fuzzy finite automata are investigated. In particular, the equivalences of deterministic and nondeterministic fuzzy tree automata, of FNBTA and FNTTA, and of FNBTA and FDBTA are discussed. The obtained results can be viewed as a foundation of further research.
