Since 2013, ICIFS has been an EUSFLAT endorsed event.
All papers accepted for presentation at ICIFS'2026 will be published in the Scopus indexed Journal "Notes on Intuitionistic Fuzzy Sets" (SJR 2024 = 0.258, Scopus quartile Q3) and will be freely available online as Open Access under CC-BY 4.0 license.
