In 1982, David Singmaster and Alexander Frey hypothesised that the number of moves needed to solve the Cube, given an ideal algorithm, might be in "the low twenties". [62] In 2007, Daniel Kunkle and Gene Cooperman used computer search methods to demonstrate that any 3×3×3 Rubik's Cube configuration can be solved in 26 moves or fewer.
There are many algorithms to solve scrambled Rubik's Cubes. An algorithm that solves a cube in the minimum number of moves is known as God's algorithm. A randomly scrambled Rubik's Cube will most likely be optimally solvable in 18 moves (~ 67.0%), 17 moves (~ 26.7%), 19 moves (~ 3.4%) or 16 moves (~ 2.6%) in HTM. [4]
Nineteen people competed in the event, and the American Minh Thai won with a single solve time of 22.95 seconds, which was, at the time, the fastest Rubik's Cube solve ever recorded. Other attendees include Jessica Fridrich and Lars Petrus , both of whom later contributed to the development of new solving methods and the speedcubing community ...
A six-year-old girl from China has set a new women’s world record for solving the 3x3x3 Rubik’s Cube in 5.97 seconds. Cao Qixian, of China’s Jiangsu Province, achieved the feat at the Rubik ...

Valk has also set three 4x4x4 world records, two for single solve and one for an average of 5. His second single world record, 26.77 seconds on 15 April 2012, was the first official 4x4x4 solve under 30 seconds. Altogether, Valk has broken 5 WCA world records, 17 European records, and 127 Dutch national records. Valk also currently holds the ...
Minh Thai (born 1965 as Thái Minh) is a Vietnamese-American speedcuber.As a sixteen-year-old Eagle Rock High School student from Los Angeles, he won the first world championship on June 5, 1982 in Budapest by solving a Rubik's Cube in 22.95 seconds. [1]
