“…In 1989, Blizard [4] introduced the concept of multiset, which is a collection of elements in which elements may occur more than once, is a generalization of a set. In recent years, multiset processing has appeared frequently in various areas of mathematics, computer science, biology and biochemistry (cf., [3,5,21,23,31]). The researchers have also used the concept of multisets in automata theory and introduced the concepts of multiset finite automata and multiset languages (cf., [6,10,11,12]), which play an important role in various areas of theoretical computer science, as in membrane computing.…”
