During 5x5 edge pairing, should you look for all 3 edge pieces, insert them into the E-layer, then slice and join them up or insert the two you can see and as you're doing that lookahead and find the third one and then join it with the 1x2 already paired? I do it the second way, idk if it's too slow and inefficient

The vast majority of the time, you'll have two edge pieces already in the E-layers and you just need to insert the last one. The only exception is right at the start of edge pairing with an absolutely minuscule chance of all 12 edge pieces in the E-layers being from different edges.

1. Two edge pieces inserted already, oriented correctly

If it's a wing and a midge, join and look ahead to inserting the missing wing piece.
If it's two wings, insert the missing wing piece then join. (Otherwise, you end up having to do a slice move to join.)

2. Two edge pieces inserted, but in opposite orientations

A few options:
(i) Choose a different edge to pair up.
(ii) Insert the missing edge piece in any orientation, then flip. (See case 3 below.)
(iii) Insert the missing edge piece while flipping another one. Try algs like R U' R2 U R or R U2 R2 U2 R.

Do any of these, then join.

3. Three edge pieces inserted in non-matching orientations

3.1. Wings match, but midge doesn't match the wings

Flip either the wings or the midge, then join.

3.2. Wings don't match

Join the matching wing and midge then flip that, or isolate the wing that doesn't match the midge and flip that.

Tsym!

Thank so you much?
Never heard that phrase before...

 

[Caden Fisher]

Can someone tell me the 11x11 edge parity alg please?

 

[Garf]

Can someone tell me the 11x11 edge parity alg please?

Uh... You just do standard big parity alg over and over again until the edge is solved. Nothing special.

Ok. Thanks

Might be a little off-topic, but an alg I learned while learning 5BLD is

Rw2 F2 U2 r2 U2 F2 Rw2.

It works on 4x4 and up for swapping two opposite edges and is faster than the traditional PLL parity alg tbh. Also saves me like 10-15 seconds on 5x5 which is amazing. The only thing you need to change for 6+ is modify the r2 layer to be the layers of whichever edges need swapped; I hope it helps!

I feel like this alg is known and some world class cuber uses this(not sebastian and not Feliks tho)

I just solved my 11x11 for the first time. Basically I was stuck on last 2 centers for like months and I just figured it out and then it took me about 35 minutes to reduce the edges and solve the 3x3.

Yeah, it is a known alg.
Rw2 F2 U2 Rw2 U2 F2 Rw2

It solves this case:

And am guessing it used by big cube solvers.

Asides from the names I've crossed out, who else in the top 20 5x5 averages uses Yau/Yau5?

Woah didn’t know Max

uses redux

 

[Noob's Cubes]

I thought he uses Yau

 

[Luke Solves Cubes]

uses redux

I thought he uses Yau

For 4x4 he uses Yau, but for 5x5 he uses redux.

 

[Noob's Cubes]

Weird.

What about 6 and 7?

 

[Timona]

Redux

There's at least Mats Valk. (recon)

I use this PLL parity for the very big cubes (6 and up), and sometimes accidentally use it on 4×4×4 as well.

And am guessing it used by big cube solvers.

Correct; it is one of the non-parity L2E cases, and anyone who remotely cares about big cubes knows this L2E alg. A huge time save over doing slice-flip-slice twice, for sure.

yau 5x5 is taking over redux.
maybe max park learning it now

 

[Timona]

Redux is definitely the future of Big cubes. Correct me if Im wrong but I think Redux has a lowermovecount that Yau. Short solves + Fast TPS = Faster times

Based on which parameters?
5x5 has been the turning point for years where nobody really gers better results with Redux or Yau so the only way this could be true is more 4x4 solver are getting into 5x5 and translate their method into other events.
