Abstract: The notion congruences and homomorphisms of Lattice-valued fuzzy finite automata is proposed,investigates some algebraic properties of congruences and homomorphisms about these automata.The main results indicate that the algebraic properties of Lattice-valued fuzzy finite automata has close connections to the algebraic properties of Lattice-ordered monoids which machines take value in.Finally studies the minimization of Lattice-valued fuzzy finite automata and provide an algorithm to achieve the minimal Lattice-valued fuzzy finite automata in virtue of regular congruence.

Key words: Lattice-ordered monoid, Lattice-valued fuzzy finite automata, congruences, homomorphsims, minimization

摘要:

给出了格值自动机的同余和同态,从代数角度出发详细研究了同余和同态关系的代数性质,揭示了格值自动机的代数性质和取值格半群的紧密联系,利用同余和同态关系最终研究了格值自动机的极小化问题,在正则同余下给出了可在有限步实现具有模糊初始状态和特殊模糊终状态的自动机极小化的算法。
