Jessica Fridrich Distinguished Professor , Fax: () URL: E-MAIL: fridrich (AT) binghamton. edu. Richard can solve the cube blindfolded and willingly shares with us his method. I met Richard in April and he showed me his incredible skills in person. The Fridrich method or the CFOP method (cross, F2L, OLL, PLL) is a fast method for solving the Rubik’s Cube created by Jessica Fridrich. It consists of four.

Rubik signed the notebook at the Rubik’s Cube World Championship in Budapest inan event where Fridrich finished tenth. The CFOP method she popularised describes solving the cube in a layer-by-layer fashion.

First, the”cross” is made on the first layer, jjessica of the center piece and four edges. The first layer corners and edges of the second layer are put into their correct positions simultaneously four pairs.

The last layer is solved by first orienting and then permuting the last layer cubies using a large number of algorithms. Fridrich first saw a Rubik’s Cube at the age of 16 in March Cubes were not immediately available to buy in communist Czechoslovakia, but Fridrich was able to acquire a Cube in July from a visiting French family.

After learning a Layer by layer technique from a Czech magazine, Fridrich was averaging around 1 minute by September. The national championship took place in May by which time Fridrich was averaging about 25 seconds. Fridrich was one of five cubers who advanced into the finals, among them, Mirek Goljan.

Fridrich won the first and second rounds and Goljan won the last third round. The second round time of Fridrich, then 17, was representing Czechoslovakia, and finished in tenth place.

Fridrich later stated that “I ended up in the exact jesscia with a baaad time This meant that the cubes favoured competitors using systems with fewer moves.

Fridrich put the CFOP system on the Internet in Januaryapparently believing “that speedcubing was inactive and not popular enough for anybody to have the motivation to go through the pain of memorizing the algorithms”.

Fridrich was actively involved in the revival of speedcubing for example meeting and encouraging a fresh-faced Dan Knights in the summer of She subsequently competed in the Caltech Winter and Cornell Spring competitions.
