Fuzzy logic is a mathematical many-valued logic that assigns truth values as a continuum, rather than as binary true or false, enabling a more flexible approach to reasoning. It is primarily applied in fields such as artificial intelligence and control theory. This book is compiled in such a manner that it will provide in-depth knowledge about the theory and practice of fuzzy logic. It presents the complex subject in the most comprehensible and easy to understand language. Coherent flow of topics, student-friendly language and extensive use of examples make this book an invaluable source of knowledge.
