Cube Scramble Generator

Overview

Cube Scrabler is a simple yet effective scramble generator for 2x2, 3x3, 4x4, 5x5, 6x6 and 7x7 Rubik's Cubes (3x3 is the default), written in Rust. It ensures no two consecutive moves are the same, providing an unpredictable and challenging scramble.

Functionality

Cube Scrambler's core function, generate_scramble, generates a random sequence of moves. The moves are denoted as "R", "L", "B", "F", "U", "D", "", "'", "2" corresponding to Right, Left, Back, Front, Up, Down, none, counter-clockwise (prime), and a 180-degree turn respectively. For the 2x2 only "R", "F" and "U" is used. The scramble generator ensures that the same move is not repeated consecutively. By default, the generator outputs 20 moves for 3x3 and 9 for 2x2. However, you can customize this by using the -c or --count argument when running the program.

Usage

Building the Project

Navigate to the project directory and build the project using Cargo:

cargo build --release

Running the Program

You can run the program with the following command:

./target/release/cube_scrambler -c 25

This generates a scramble of 25 moves. If you don't specify the -c or --count option, the program defaults to generating 20 moves.

Dependencies

This project depends on the rand and argparse crates. These are specified in the Cargo.toml file in the project's root directory.

Conclusion

Whether you're a beginner or a seasoned Rubik's Cube solver, the Cube scramble generator provides an easy-to-use tool for generating a variety of scrambles. It's flexibility in the number of generated moves allows for a wide range of scramble complexities. Happy cubing!
