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.

Jessica Fridrich – Wikipedia

Y ou would have a full visibility on all the unsolved pairs. This corner and edge are called a pair. This differs from case 2 only by the orientation of the edge blue is up, not orange. Thankfully, you do not need to learn everything at once and each of these two steps can be separated in two sub-steps. How to Solve the Rubik’s Cube. It helps you to focus on unsolved faces, instead of focusing on the white face.

The first two layers F2L 4 Step 3 of Fridrich method: It is now time to start practicing! This will be very useful if you want to communicate with other speedcubers about a specific algorithm. The cross is done intuitively. Every PLL can be performed in under a second by the best speedcubers.


Jessica Fridrich is a professor at Binghamton Universitywho specializes in data hiding applications in digital imagery. Some other times, we build the pair and insert it at the same time. Once you can do any cross blindfolded, you will be able to focus on the first pair while solving the cross.

Here there are two different cases. Fridrich method is also called CFOP. But we are going to use either the one or the other depending on the case. A tip for training is to do the cross blindfolded.

You already know the two formulas. I would recommend you to start with these ones. The cases described below are designed to help you gain that intuition.

Categories Cubers Method inventors Speedcubers. This will make you save huge amounts of time. Either one face is completely finished or none is. Everyone has his own metjod and his way of solving the cross.

Once finished, a D2 move aligns the cross. Also remember that you have two hands and the left hand should not only be used to hold the cube.

During pre-inspection, take more than 15 seconds. A lot mrthod algorithms to learn. First a so-called “cross” is made on the first layer, consisting of the center piece and four edges. In the Fridrich method, the last layer is solved differently from the beginners method. This page was last edited on 17 Decemberat They will be presented with an example.


Computer Engineering Professor Years Active: All the algorithms for this step are super easy and can be tridrich under a second. The national championship took place in May by which time Fridrich was averaging about 25 seconds. The last layer is solved by first orienting and then permuting the last layer cubies using a large number of algorithms.

Don’t forget mthod align the centers pieces of the cube! Now you have everything to find the best F2L algorithms using Fridrich method.

To do that we will need to flip the corners and the edges. Most of the time, what frodrich you down is your inspection and your thinking. Here are the magic algorithms:.

Every second you do not rotate any face can be saved. I would advice you to get the MoYu Aolong v2, best speed cube ever! Jessica Fridrich works as a professor at the Department of Electrical and Computer Engineering at Binghamton University and specializes in digital watermarking and forensics.

It definitely turns much better than my other speed cubes.

If you do UF’U2, you can turn this case into case 2 above. Good control of the cube.
