Rubik’s Cube is a classic 3D puzzle game that has been popular for over 40 years. It was invented by Erno Rubik, a Hungarian architect and professor of architecture, in 1974. The puzzle consists of a cube with six faces, each composed of nine smaller cubes, which can be rotated along their axes. The goal of the game is to solve the puzzle by making each face a single color.

In recent years, solving Rubik’s Cube has become a popular challenge for computer programs. While the puzzle can be solved by human intuition and pattern recognition, computer algorithms can be used to solve the puzzle more efficiently and quickly. In this post, we’ll explore the history of Rubik’s Cube and how it has been used to challenge computer programming.

##### History of Rubik’s Cube:

Rubik’s Cube was invented in 1974 by Erno Rubik, a professor of architecture in Hungary. Rubik was looking for a way to teach his students about 3D objects and their properties. He created the puzzle by combining six individual cubes that could rotate independently of each other. He initially called the puzzle the “Magic Cube,” but it was later renamed “Rubik’s Cube” when it was released to the public in 1980.

The puzzle quickly became a sensation, with millions of copies sold worldwide. It was particularly popular in the 1980s, when it became a cultural icon and was featured in movies, TV shows, and music videos. The Rubik’s Cube was also the subject of world championships, with speedcubers competing to solve the puzzle in record time.

##### Rubik’s Cube and Computer:

While humans have been solving Rubik’s Cube for decades, the puzzle has also been a popular challenge for computer programming. In fact, the first Rubik’s Cube solver was developed by computer scientist Herbert Kociemba in the 1980s. Kociemba used a technique called “group theory” to develop an algorithm that could solve the puzzle in just 20 moves.

Since then, many computer programs have been developed to solve Rubik’s Cube. Some of these programs use brute-force methods to search through all possible combinations of moves to find the solution. Other programs use more sophisticated algorithms that take advantage of patterns and symmetries in the puzzle to solve it more efficiently.

One notable example of a Rubik’s Cube solving program is the CubeStormer II, developed by a team of British engineers in 2011. The CubeStormer II uses a combination of computer vision and machine learning to solve the puzzle in just 5.27 seconds. The program uses a smartphone camera to scan the puzzle, and then calculates the solution using a powerful algorithm running on a Samsung Galaxy S II smartphone.

Another interesting development in Rubik’s Cube and computer programming is the use of genetic algorithms. Genetic algorithms are a type of artificial intelligence that mimic the process of natural selection. They work by creating a population of solutions, and then breeding the best solutions together to produce new, better solutions.

In the case of Rubik’s Cube, genetic algorithms can be used to find the optimal solution to the puzzle. Researchers have used genetic algorithms to find solutions to Rubik’s Cube that require fewer moves than the current world record. For example, in 2018, researchers at the University of California, Irvine used a genetic algorithm to find a solution that required just 26 moves.

##### Conclusion:

Rubik’s Cube is a classic puzzle game that has been popular for over 40 years. While the puzzle can be solved by human intuition and pattern recognition, computer algorithms can be used to solve the puzzle more efficiently and quickly. Over the years, many computer programs have been developed to solve Rubik’s Cube, using a variety of techniques and algorithms. These programs have demonstrated the power of computer algorithms to solve complex problems and have pushed the limits of what is possible in the world of Rubik’s Cube solving.

The development of Rubik’s Cube solving programs has also had practical applications in fields such as robotics and computer vision. For example, the CubeStormer II program, which uses computer vision and machine learning to solve Rubik’s Cube, could be used in industrial automation or manufacturing. The algorithm could be adapted to recognize and sort different objects based on their color or shape.

In addition to its practical applications, the Rubik’s Cube has also become an important benchmark for computer science research. The puzzle provides a challenging and well-defined problem that can be used to test the performance of different algorithms and techniques. By developing algorithms that can solve Rubik’s Cube, researchers can gain insights into how to solve other complex problems in fields such as optimization, machine learning, and artificial intelligence.

Overall, the Rubik’s Cube is a classic puzzle game that has captured the imaginations of millions of people around the world. While the puzzle can be solved by human intuition and pattern recognition, computer algorithms have pushed the limits of what is possible in Rubik’s Cube solving. As technology continues to advance, it will be exciting to see how computer algorithms will continue to push the boundaries of Rubik’s Cube solving and other complex problems in the years to come.
