If the perturbation formula of the Rubik's cube is not solved, the computer can also calculate the minimum steps to restore the Rubik's cube. The reduction step of Rubik's cube belongs to a mathematical probability analysis. It's just that he is a powerful probability analysis, unlike the simple probability analysis that we usually study mathematics. Computers are programmed, so computers are very good at this kind of probability analysis. Like the Rubik's Cube that we play most often, it is generally composed of 26 small pieces, and these 26 small pieces of Rubik's Cube are like a coordinate system, so the computer will analyze the coordinates of each small piece and its trajectory, so that he can accurately calculate every possibility.
So which formula can the computer itself work out? (8! * 38 *12 * 212)/3 * 2 * 2 = 43, 252, 003, 274, 489, 856, 000 third-order Rubik's Cube, one * *, and there are so many possibilities. And there is only one possibility among these possibilities. It's exactly the same to be able to turn to six faces. So the amount of calculation is quite large. Generally speaking, only people with clear thinking and quick brain rotation can quickly spell out this Rubik's cube.
