چکیده

In the paper we continue studying essential inputs of trees and automata initiated in [10]. We distinguish the behavior of the essential inputs of trees and essential variables for discrete functions. Strongly essential inputs of trees are introduced too. It is proved that if a tree and an automaton have at least two essential inputs then they have at least one strongly essential input. A minimization algorithm for trees and automata is proposed. Various examples for application in Computer Science are shown. AMS, subject classification: 03D05, 68Q70, 03D15, 06B25

Tree Automata and Essential Input Variables

We introduce the essential inputs (variables) for terms (trees) and tree automata. It is proved that if an input xi is essential for a tree t and an automaton A then there is a chain of subtrees connecting xi with the root of t such that xi is essential for each subtree belonging to this chain. There are investigations which treat some rules for removing and adding of fictive (non-essential) in...

Multidimensional fuzzy finite tree automata

This paper introduces the notion of multidimensional fuzzy finite tree automata (MFFTA) and investigates its closure properties from the area of automata and language theory. MFFTA are a superclass of fuzzy tree automata whose behavior is generalized to adapt to multidimensional fuzzy sets. An MFFTA recognizes a multidimensional fuzzy tree language which is a regular tree language so that for e...

NEW DIRECTION IN FUZZY TREE AUTOMATA

In this paper, our focus of attention is the proper propagationof fuzzy degrees in determinization of $Nondeterministic$ $Fuzzy$$Finite$ $Tree$ $Automata$ (NFFTA). Initially, two determinizationmethods are introduced which have some limitations (one inbehavior preserving and other in type of fuzzy operations). Inorder to eliminate these limitations and increasing theefficiency of FFTA, we defin...

TREE AUTOMATA BASED ON COMPLETE RESIDUATED LATTICE-VALUED LOGIC: REDUCTION ALGORITHM AND DECISION PROBLEMS

In this paper, at first we define the concepts of response function and accessible states of a complete residuated lattice-valued (for simplicity we write $mathcal{L}$-valued) tree automaton with a threshold $c.$ Then, related to these concepts, we prove some lemmas and theorems that are applied in considering some decision problems such as finiteness-value and emptiness-value of recognizable t...

MINIMAL AND STATEWISE MINIMAL INTUITIONISTIC GENERAL L-FUZZY AUTOMATA

In this note, by considering the notions of the intuitionistic general L-fuzzy automaton and $(alpha, beta)$-language, we show that for any $(alpha, beta)$-language $mathcal{L}$, there exists a minimal intuitionistic general L-fuzzy automaton recognizing $mathcal{L}$.We prove that the minimal intuitionistic general L-fuzzy automaton is isomorphic with threshold $(alpha,beta)$ to any $(alpha, be...
