I've added some commutator and conjugate explanations on the wiki :

I've done the optimization of sequences for grip (by adding rotations and using double moves instead of simple moves).
The scrambe can also be grip-optimized.
Here is an example :
B2 L2 B' R' B' U' L2 R2 D' B2 L2 F' B' L2 U D' B' R L2 U D R2 L' F2 L'
is optimised in :
y R2 x' U2 R' u' f' U'...
New version with grip evaluation.

There is now a Grip button at the bottom left of the form. You can choose right-handed or left-handed.
I am still wishing to do some kind of optimal OLL and optimal PLL solver. That's why I didn't go directly toward automatic application of these algorithms. But if I can't find out how to do it, well I suppose I can do some automatic recognition of cases and rotation of those algorithms.
I am...
Here is my lastest program. It is a Rubik's cube program that solves the first two layers using the F2L method.
You can turn the cube in 3D and move faces using F, U, L, B, D, R, with Shift and Alt. Also you can use M, E, S for slice moves, and x,y,z to rotate the cube with the keyboard...
Hello!
Here is a video to explain how to orient corners, which is part of OLL, but without using algorithms. Here every move is explained. Well, the basic 3-cycle is very briefly explained, so if you want more explanation, see the other video below that explains commutators.
My english...
No, it would be
(R' (U L' D2 L U' L' D2 L) R)(F2 U') (M' U2 M) (U' F2)
That's a bit complicated for me. But thinking about it, I found this one to do the R perm :
(M2 U2 M2)(U L' R' d2 R U R' d2 R U' L)(M2 U2 M2)
Sure. Why not.
I can't find the T perm and the F perm. Well for example, the F...
Thanks Godmil :)
@cmowla: Yeah I'm getting a little bit lost with conjugating big commutators.
But I found one that is interesting :
(L' U' L U) + (U R U' L d2 L' U L d2 L' R') + (U' L' U L)
(conjugate) + (J perm) + (deconjugate)
Which gives Y perm.
It can be simplified to
L' U' L + L U' R...
Ok I got it. The setup move is merged with the commutator, and it moves the two corners instead of moving the buffer corner.
I still do not understand your move. But I kinda understand the principle you've used.
That's interesting. I didn't think about it. Is it really shorter than combining...
