Weakly linear systems of fuzzy relation inequalities and equations have recently emerged from research in the theory of fuzzy automata. From the general aspect of the theory of fuzzy …

Recently, two types of simulations (forward and backward simulations) and four types of bisimulations (forward, backward, forward–backward, and backward–forward bisimulations) …

We show that the state reduction problem for fuzzy automata is related to the problem of finding a solution to a particular system of fuzzy relation equations in the set of all fuzzy …
J Ignjatović, M Ćirić, S Bogdanović - Fuzzy Sets and Systems, 2010 - Elsevier
In this paper we study systems of fuzzy relation inequalities and equations of the form U∘ Vi≤ Vi∘ U (i∈ I), where U is an unknown and Vi (i∈ I) are given fuzzy relations, the dual …

We improve on an existing [PA Abdulla, J. Högberg, L. Kaati, Bisimulation minimization of tree automata, International Journal of Foundations of Computer Science 18 (4)(2007) 699 …
We address the problem of computing simulation relations over tree automata. In particular, we consider downward and upward simulations on tree automata, which are, loosely …

Forward and backward bisimulations have been introduced recently by Ćirić et al.(2012)[9] as a means for modeling the equivalence between states of fuzzy automata and …
M Ćirić, J Ignjatović, M Bašić, I Jančić - Information Sciences, 2014 - Elsevier
In this paper we study the equivalence of nondeterministic automata pairing the concept of a bisimulation with the recently introduced concept of a uniform relation. In this symbiosis …
