It has been shown that the algebraic study of automata theory played a key role in the development of fundamentals of computer science. This book demonstrates some algebraic aspects of fuzzy automata, fuzzy Multiset automata and rough automata and its languages. Specifically, this text presents the foundations of algebraic theory and languages of these automata which will attract the researchers and will help in finding some successful applications of these types of automata theory. Ideas for future research and explorations are also provided. Students and researchers groups in computer...
