🧩The number of moves to solve a Rubik's Cube can be measured, and the current world record is 4.73 seconds.
📈A new approach to solving the Rubik's Cube is to measure the number of moves instead of time, leading to more efficient algorithms.
🔢Every Rubik's Cube can be solved in at most 20 moves, which was proven in 2010.
🌐The configurations of a Rubik's Cube can be represented as a graph, and finding the shortest solution is equivalent to finding the shortest path in the graph.
💡The meet-in-the-middle algorithm allows for searching from both ends of the graph simultaneously, reducing the time and memory complexity of finding the shortest solution.
