5movei rulz, also known as the 5-move rule, refers to the idea that any Rubik's Cube can be solved in 20 moves or less. This rule has been proven mathematically and has been used to create algorithms for solving the Rubik's Cube.
The 5-move rule is important because it provides a theoretical upper bound on the number of moves required to solve the Rubik's Cube. This means that no matter how difficult a Rubik's Cube puzzle may seem, it can always be solved in 20 moves or less. The rule has also been used to develop more efficient algorithms for solving the Rubik's Cube, making it possible to solve the puzzle in fewer moves than the 20-move upper bound.
The 5-move rule was first discovered by David Singmaster in 1995. Singmaster showed that any Rubik's Cube can be solved in 20 moves or less by using a combination of five basic moves. These five moves are:
- Front (F)
- Back (B)
- Left (L)
- Right (R)
- Up (U)
- Down (D)
The 5-move rule has been used to develop a variety of algorithms for solving the Rubik's Cube. These algorithms typically involve a series of specific moves that are designed to solve the cube in the fewest possible moves. While the 5-move rule does not guarantee that you will be able to solve the Rubik's Cube in 20 moves or less, it does provide a theoretical upper bound on the number of moves required. This can be a helpful benchmark for Rubik's Cube solvers, and it can also help to develop more efficient solving algorithms.
