Even though I didn’t really understand it at the time of purchase, the reviews sold me that this genius intuitive technology would result in the perfectly cooked rice I desired. And it did.
First the name. A crisp relation represents presence or absence of association, interaction or interconnection between elements of ≥ 2 sets. Therefore, if it isn’t a crisp relation – not a straight defined process – it is a case of a fuzzy relation.
Fuzzy-logic rice cookers have computer chips that direct their ability to make proper adjustments to cooking time and temperature. Unlike basic rice cookers, which complete tasks in a single-minded, mechanical manner, the process behind the fuzzy-logic rice cookers is actually based on math.
In contrast to the Boolean logic where the truth values of variables may only be the integer values 0 or 1, fuzzy logic is a form of many-valued logic.
The fuzzy sets theory, first proposed by UC Berkeley professor Lotfi Zadeh in 1965, laid the groundwork for fuzzy logic. Fuzzy sets theory has to do with mathematical sets. An element either belongs to the set or it doesn’t. For example, a sparrow would belong to a set of birds, but a bat wouldn’t. In fuzzy logic, though, elements can belong to sets in varying degrees. This might make the taxonomists among us start to twitch.
Using numbers, it incorporates non-definitive words like “slightly” or “almost” into its decision-making processes. As a result, the use of fuzzy logic in rice cookers helps to ensure properly cooked rice because it gives the appliances the ability to make judgment calls similar to those a person might make. It is fair to say those decisions might be better than those a hungry, impatient person might make.
Using fuzzy logic, different logic values can be assigned. Variables between the extremes of zero and one are closer to the concept of probability, which means there is a major correlation between the science of probability and fuzzy logic. However, fuzzy logic refers to intensity of truth, while probability refers to likelihood.
