Frank Morris (born August 25, 1981 in Boise, Idaho) is an American competitive speedcuber.. He is best known as the 2005 World Champion for solving the Professor's Cube.He is also known for having held World Cube Association recognized world records for both the Rubik's 4×4×4 cube single solve time, as well as the Rubik's 5×5×5 cube single solve time and average time.
God's algorithm is a notion originating in discussions of ways to solve the Rubik's Cube puzzle, [1] but which can also be applied to other combinatorial puzzles and mathematical games. [2] It refers to any algorithm which produces a solution having the fewest possible moves (i.e., the solver should not require any more than this number).
The maximal number of face turns needed to solve any instance of the Rubik's Cube is 20, [2] and the maximal number of quarter turns is 26. [3] These numbers are also the diameters of the corresponding Cayley graphs of the Rubik's Cube group. In STM (slice turn metric) the minimal number of turns is unknown, lower bound being 18 and upper bound ...
A solved Rubik's 360 puzzle. Rubik's 360 is a 3D mechanical puzzle released in 2009 by Ernő Rubik, the inventor of Rubik's Cube and other puzzles. [1] Rubik's 360 was introduced on February 5, 2009 at the Nürnberg International Toy Fair [2] ahead of its worldwide release in August.
[2] For most events, an average of five is taken, but for 6×6×6, 7×7×7, 3×3×3 blindfolded, 3×3×3 fewest moves, 4×4×4 blindfolded and 5×5×5 blindfolded, an average of three is taken. For averages of five solves, the best time and the worst time are dropped, and the mean of the remaining three solves is taken.
The Professor's Cube (also known as the 5×5×5 Rubik's Cube and many other names, depending on manufacturer) is a 5×5×5 version of the original Rubik's Cube. It has qualities in common with both the 3×3×3 Rubik's Cube and the 4×4×4 Rubik's Revenge , and solution strategies for both can be applied.
Petrus grew up in Gammelstaden just outside of Luleå. [4]He took up speedcubing in the early 1980s, learning it over the course of a summer when he was unemployed. [5] In 1982, he became the national champion of Sweden, and went on to finish fourth overall at the first official Rubik's Cube World Championships held in Budapest, Hungary.
