I'm not sure if you're mistaken or just disregarding a horrible parity case.

Have you ever heard of the "three-color rule"?

Scroll about 2/3 of the way down.

Actually I have heard of it, but too much work . I prefer to be CN and go for easy cross than actually think about it.

This is not exactly true. When I have an O-perm, they are in correct relation to each other. This means, I will have to add corners into my recognition. Detecting "3x3 PLLs" isn't the best method, I guess.

I also tried to detect patterns like Dan does but I have a weird system which doesnt work well, at least for me.

Any other ideas?

If the corners are solved and the edges are correct in relation to each other, there are only 3 possibilities: solved, H perm, and O perm. You should be able to tell those three apart.

(Sorry for my English )

By Reason of the terrible ([-]x, -x) move (for me), I used the method in this thread.
I found 2 more algs (Inverted), which don't use this move, except of the last move.

NA: / (3, 3) / (1, 0) / (-2, 0) / (4, 0) / (-4, 0) / (-2, 0) / (-1, 0) / (-3, -3) (matching bar at DL)
OA: / (3, 3) / (1, 0) / (-2, 0) / (4, 0) / (-4, 0) / (-2, 0) / (5, 0) / (-3, -3) (matching bar at DR)

Oh nice! Those algs are sooo much better than the other ones!

Now we just need good N/N or O/O whatever you want to call it.

For NN I use the Adj-Alg (I do a normal Vandenbergh Solution at CP-Skip). I'm able to execute that algorithm in 4 Seconds.
For OO I currently use the "normal" Alg and then the Adj-Alg.

I'm so sorry. This hasn't been replied to for 6 1/2 years, but I need to know:

Is this for corner or edge? Because the edges don't seem to move, only the corners

This solves parity during corner permutation instead of during edge permutation. The main pro to it is that it has less algs to learn, but now that cubeshape parity is a thing, this should probably be disregarded if you want to get world class.

I have two adjacent edges that need to be swapped. Do I do AN or NA?

The list of algs in the OP doesn't include the NN case, which is what you're looking for. Just use any parity EP alg instead.

Thanks that helped!
