This is a math oddity that so far has always ended in the loop of 4, 2, 1. (Note) I don't know if the engine breaks after certain #e+# like 1e+56.
Credit to the Collatz conjecture, for making this project possible. WARNING: THE EXPLANATION BELOW IS LONG AND COMPLICATED. IF YOU DO NOT WISH TO INJURE YOUR BRAIN, DO NOT SCROLL DOWN! Here is the probability factor: according to the math, when you have an odd, no matter what, the rule will make it even. That can in turn be divided by two to equal either an even or an odd number. 50/50 chance for each number. So if it lands on even, the next divide there will be a 25/75 chance it lands on even v.s. odd. The chance for an even number will slowly decrease based on the amount of times in a row you have gotten it. The law of probabilities states that if there is a even chance for something to happen, then the more it happens the less of a chance you will have in the grand scheme of things. Back to the probability factor. If the even divides and lands on odd, then the next time you multiply it will again be an even. Then you repeat the chances until you get odd. Basically, every odd will turn into an even. Every even could either turn into itself or an odd. Even makes the number smaller, odd makes the number bigger. So when you have more chances or turns to make a number smaller, the number will gradually decline in value, no matter which number it is.
