The method developed by Jessica Fridrich involves memorizing a lot of algorithms, but there is a logical connection between them. ![]() These steps are the following: Cross, F2L, OLL and PLL, as seen on the illustration above. ![]() This advanced technique developed by Jessica Fridrich divides the puzzle into layers and you have to solve the cube layer by layer using algorithms in each step, not messing up the pieces already in place. In 2018, Fridrich was elected a fellow of the National Academy of Inventors.When talking about the advanced technique of solving the Rubik's Cube we have to mention the Petrus system and the Fridrich method (or full CFOP) which is used by the big majority of speedcubers these days. ![]() She received her MS degree in applied mathematics from the Czech Technical University in Prague in 1987, and her PhD in systems science from Binghamton University in 1995. Jessica Fridrich works as a professor at the Department of Electrical and Computer Engineering at Binghamton University and specializes in digital watermarking and forensics. She competed in Rubik's Cube World Championship in Budapest in 1982 in which she finished 10th with the best time of 29.11 seconds Career The specific time of 23.55 seconds during the second round paved the way for Fridrich to secure the top spot. In this arena, Fridrich clinched victory in both the initial and second rounds, whereas Goljan secured the triumph in the third and final round. Out of the participants, five cubers, including Mirek Goljan, advanced to the finals. In May 1982, the national championship occurred, coinciding with Fridrich's average solve time hovering at approximately 25 seconds. By the time September rolled around, she had reached an average solving time of roughly 1 minute. Following the acquisition of the Cube, Fridrich delved into learning a Layer by Layer technique from a Czech publication. However, Fridrich managed to obtain one in July when a French family visiting the area brought it along. These cubes weren't immediately purchasable in the context of communist Czechoslovakia. The last layer is solved by first orienting the yellow pieces (OLL) and then permuting the last layer of the cube using a few sets of algorithms (PLL).Īt the age of 16, in March 1981, Fridrich saw a Rubik's Cube for the first time. Next, the first layer's corners and edges of the second layer are put into their correct positions simultaneously in pairs (F2L). First a "cross" is made on the first layer, consisting of the center piece and four edges (Cross). The method describes solving the cube in a layer-by-layer fashion. Nearly all of the fastest speedcubers have based their methods on Fridrich's, usually referred to as CFOP, that is, (Cross, First 2 Layers, Orientation of the Last Layer, Permutation of the Last Layer). She is considered one of the pioneers of speedcubing, along with Lars Petrus. 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. Jessica Fridrich (born Jiří Fridrich) is a professor at Binghamton University, who specializes in data hiding applications in digital imagery.
