moreIn this paper, we introduce the concept of doubt intuitionistic fuzzy subalgebras and doubt intuitionistic fuzzy
ideals in BCK/BCI-algebras. We show that an intuitionistic fuzzy subset of BCK/BCI-algebras is an
intuitionistic fuzzy subalgebra and an intuitionistic fuzzy ideal if and only if the complement of this
intuitionistic fuzzy subset is a doubt intuitionistic fuzzy subalgebra and a doubt intuitionistic fuzzy ideal. And
at the same time we have established some common properties related to them.
