... to continue from the earlier post, I had a phone call and wrapped it up too soon .... However, fuzzy logic is only one way to get such an effect. You can get the same using Neural Nets and some sort of learning algorithm. https://en.wikipedia.org/wiki/Artificial_neural_network Or you can try some sort of Genetic algorithm see: https://en.wikipedia.org/wiki/Genetic_algorithm These ways to go after the same problem And we have Python packages for this, too. The thing is that these things, aside from being suitable for a whole lot of problems where you really want the outside environment to influence the result of your code, don't have a lot in common. So, among practicioners of these arts -- mostly found designing AI and control systems -- there doesn't seem to be a pressing need for a general term that includes any of these. And, at least in the area of control systems, there is a real problem with the testing of such things. They have this unfortunate habit of producing results that were undreamed of by their creators, which is not what you want in the control system for your high-speed train -- or especially if you are the insurance underwriters for that same train. So there is rather more effort spent on going the other way -- writing code that does the job but which is less and less dependent on outside factors than in finding ways to include more outside factors in the code we already have.
