Cube mid-solve on the OLL step. The CFOP method (Cross – F2L (first 2 layers) – OLL (orientate last layer) – PLL (permutate last layer)), also known as the Fridrich method, is one of the most commonly used methods in speedsolving a 3×3×3 Rubik's Cube. It is one of the fastest methods with the other most notable ones being Roux and ZZ.
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.
Additionally, specialized formats such as 3×3, 4×4, and 5×5 blindfolded, 3×3 one-handed, 3×3 Fewest Moves, and 3×3 multi-blind are also regulated and hosted in competitions. [ 1 ] As of December 2024, the world record for the fastest single solve of a Rubik's cube in a competitive setting stands at 3.134 seconds.
The method he used is called IDA* and is described in his paper "Finding Optimal Solutions to Rubik's Cube Using Pattern Databases". [19] Korf describes this method as follows IDA* is a depth-first search that looks for increasingly longer solutions in a series of iterations, using a lower-bound heuristic to prune branches once a lower bound on ...
The Rubik's Cube world champion is 19 years old an can solve it in less than 6 seconds. While you won't get anywhere near his time without some years of practice, solving the cube is really not ...
Over a span of years, Gilles Roux developed his own method to solve the 3x3x3 cube. Using a smaller quantity of memorized algorithms than most methods of solving, Roux still found his method to be fast and efficient. The first step of the Roux method is to form a 3×2×1 block. The 3×2×1 block is usually placed in the lower portion of the ...
Jessica Fridrich (born Jiří Fridrich) is a professor at Binghamton University, who specializes in data hiding applications in digital imagery.She is also known for documenting and popularizing the CFOP method (sometimes referred to as the "Fridrich method"), one of the most commonly used methods for speedsolving the Rubik's Cube, also known as speedcubing.

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 ...
