On the solvability of weakly linear systems of fuzzy relation equations☆

S Stanimirović, I Micić - Information Sciences, 2022 - Elsevier
Abstract Systems of fuzzy relation equations and inequalities in which an unknown fuzzy

Computing the fuzzy partition corresponding to the greatest fuzzy auto-bisimulation of a fuzzy graph-based structure under the Gödel semantics

LA Nguyen - Information Sciences, 2023 - Elsevier
The similarity measure based on fuzzy bisimulation has the Hennessy-Milner property as a
strong logical foundation. It is useful for classification and clustering. In this work, we design …
