# JESSICA FRIDRICH ALGORITHMS PDF

It is the key to solve the cube under 20 seconds or even 10 seconds if you really master the method. This method is named after its creator, Jessica Fridrich. He said: “I am using the Fridrich method.” I asked with a surprise in my voice: ” You actually memorized ALL algorithms?” His answer was: “No. 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.

If you perform each algorithm as quickly as humanly possible, you don’t leave yourself much time to analyse the cube and isolate the next corner-edge pair you want to solve. Fortunately, there is a huge algorithm database for your perusal, where you can find the perfect algorithms for you.

Instead, the pieces that do get affected are ones you don’t care about, as they were occupying the space that you want to put the red-blue pair into. Both have the same effect, but a double layer turn is quicker. Instead, it is much better to perform the algorithms slightly more slowly in one continuous stream.

As you might well imagine, this means that full CFOP has a lot of algorithms in it – one for every situation you might encounter. You want a taste of the high-flying, rock and roll lifestyle of the speedcuber. Fridrich won the first and second rounds and Goljan won the last third round.

But you could also place the white-red piece by doing this:. The formulas can seem a bit long but they are uessica easy to learn. Try to also remember that you probably have fridricj hands. The CFOP method she popularised describes solving the cube in a layer-by-layer fashion. The OLL skip is the position where all the last layer is already oriented without performing any algorithm.

Everyone has his own technique and his way of solving the cross. The second option is this algorithm:. The algorithm page has each OLL algorithm ordered by the shape they resemble, so you can find which situation you need easily.

Even if you understand the basic ideas above, it isn’t always obvious how best to proceed. I am going to give you a few techniques to solve these cases. 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. Now that you know the beginner algorithmx, you can begin to introduce the concepts in this guide into your solves.

Fridrich first saw a Rubik’s Cube at the age of 16 in March Have a go on your cube, and see if you can work out how to solve any of the pairs. This is the fastest and the easiest Rubik’s cube solving method. If you’ve just jeszica at this website looking to learn how to solve a Rubik’s Cube and thought to yourself “Beginner my left foot, I’m starting with the speed cubing guide, that sounds fast”, then I warn you now: Rather than relying on a big table of algorithms, F2L is best done intuitively.

Once you have located the two corners that are of the same color, the other two need to be permuted. It is possible that solving the cross on the bottom wastes time in the beginning but it will quickly make you jeswica.

Once you can do any cross blindfolded, you will be able to focus on the first pair while solving the cross. Well here is where your journey begins.

It consists of four steps: Maybe you’re even getting pretty good, and can consistently do it in under 2 minutes.

First a so-called “cross” is made on the first layer, consisting of the center piece and four edges. You may be tempted to solve this case with your right hand. Retrieved April 19, You should do it on the bottom because then it’s easier to locate the other pieces.

You simply repeat these steps for each of algirithms four corners, and solve each F2L pair in turn. This page was last edited on 17 Decemberat This page was last edited on 12 Septemberat Then, fridrivh you know uessica few algorithms, you can begin to learn the rest of the last layer algorithms while always being able to fall back on the ones you know.

They were used the one after the other in the step 7 of the beginners method. To algoithms it fully there are about 80 algorithms to learn and that is why I am going to first frivrich an intermediary method.

It’s ok, no one has to know. Not having to turn the cube over after completing the cross on the top layer saves a lot of time, and it also means that you can be looking for the pieces for the next step whilst completing the cross on the bottom. This step is called CPLLas it aims to permute the corners – that is, move them to their correct positions like this:. It’s beautiful, and no horrid cube rotations.

Fridrich method is also called CFOP.

## How to Solve the Rubik’s Cube/CFOP

Also remember that you have two hands and the left hand should not only be used to hold the cube. There are, however, a few situations you might find yourself in where this procedure is not quite so obvious.

Sometimes, it is easier to first build the pair and then insert it. Why don’t you give it a try – go to the timer pageset inspection time to 15 seconds and see if you can produce a solution to the cross entirely in your head.

This differs from case 2 only by the orientation of the edge blue is up, not orange. They are there so you can see an optimal way to solve each case, but try to not rely on them for every single F2L case you encounter. But not exactly the same, as you’ll have noticed – the cube is upside down. If you do RU2R’, you can turn this into case 3.

PLL gets the same treatment, as we’ll be permuting the corners first and then the edges. The corner firsts methods that were the best at the time did not allow such a fast vision.
