What are the benefits of "fuzzy logic" in a rice cooker?
I just purchased a Zojirushi rice cooker a couple of months ago and can’t imagine cooking rice without it now.

Fuzzy logic in comparison to binary logic is a varying degree of a state.  In binary logic an item is either true or false (on or off) but in fuzzy logic it can be in between, partially on or partially off.  Instead of hard “done” state the fuzzy logic states may be “somewhat” or “nearly” done.  This while cooking it could take on the meaning of” too hot”, “about right” or “not much change”. Where this comes into play in a rice cooker is when the sensor monitoring the water content reaches the critical point an ordinary cooker will just turn off the heater however, a fuzzy logic cooker will use an equation (usually derived from experimentation) to vary the temperature and optimize the amount water being absorbed and evaporated.  Typically a fuzzy logic system will have multiple “critical” points and will vary the temperature during ramp up and down as well as during the cooking. Generally, different types of rice will absorb different amounts of water at different rates.  The fuzzy logic circuitry will monitor the changes and adjust itself to accommodate the predetermined profile.

I guess you could say the benefit of a fuzzy logic cooker is that someone took the time to learn the complexities of the cooking process and characteristics of the rice then adapted the preparation process to match the “ideal” conditions for the perfect rice.
