International Conference on Intuitionistic Fuzzy Sets is a scientific meeting devoted to the intuitionistic fuzzy sets, held in Sofia or Varna, Bulgaria annually since 1997 year. It is organized on the basis of a bilateral agreement for scientific cooperation between Institute of Biophysics and Biomedical Engineering at the Bulgarian Academy of Sciences and Systems Research Institute at the Polish Academy of Sciences.
The papers, presented at the conference, are published in the journal "Notes on Intuitionistic Fuzzy Sets".
