What type of logic utilizes more than two truth values?

Fuzzy logic is distinguished by its use of more than two truth values, unlike traditional forms of logic like Boolean logic, which relies on binary values (true or false). In fuzzy logic, truth values can range anywhere between 0 and 1, allowing for degrees of truth. This characteristic enables fuzzy logic to effectively handle uncertain or imprecise information, making it especially useful in applications such as control systems, artificial intelligence, and decision-making processes where binary distinctions may be overly simplistic.

This flexibility allows fuzzy logic to model real-world scenarios more accurately, where values often exist in shades rather than discrete categories. By allowing for a continuum of truth values, fuzzy logic can better represent the complexities of certain problems that cannot be adequately addressed through traditional binary logic systems.
