There is a computer program that can solve a Rubik's Cube in under 0.5 seconds.
In 2013, a team of computer scientists from the University of California, Berkeley, developed an algorithm that can solve a Rubik's Cube in 0.38 seconds. The program, called "Korf," uses a combination of mathematical formulas and search algorithms to find the optimal solution. The team's achievement shattered the previous record, which was held by a program that solved the cube in 2.04 seconds. The program's speed and efficiency have been widely recognized as a significant breakthrough in computer science.
