I didn't call it this but I've had this idea too (a long time ago). Unfortunately flipping stuff is so move-intensive that this idea is essentially useless for speed, OH, and FM.

We basically came to the same conclusion. Was fun to research though. I just named it this because I didn't want to just say PLL/OLL - I knew that others would've thought of it before.

As for "pure OLL" though, if you're going to go 2-look, I really recommend doing corners first. Edges are easy to do with MU algs, but the more complex corner flips are pretty ugly, and I imagine there are much nicer ones out there if you allow some edges to be flipped too.

tru.dat. I only suggested it because /some/ of the corners flips are nice and I thought they all be. I didn't realise the rest were dire until writing it out.

We never generated all the PureOLL algs

Bernard and Mirek did, though:

Yah, we saw these and concluded that they sucked. I actually meant that we never generated /good/ algs. ^_^

Posting LSE stuff because my LSE is fast enough and I don't know anymore tricks.

I've realised that I need to work on my second block.

Here are my stats for the first block;

2.42, 2.07, 2.51, 2.39, (2.79), 1.78, 1.39, (1.32), 2.08, 2.64, 2.14, 1.63 = 2.11

Here are my stats for the first two blocks;

number of times: 100/100
best time: 4.88
worst time: 11.58

current avg5: 6.87 (σ = 0.19)
best avg5: 5.91 (σ = 0.60)

current avg12: 6.77 (σ = 0.66)
best avg12: 6.43 (σ = 0.82)

current avg100: 7.26 (σ = 1.29)
best avg100: 7.26 (σ = 1.29)

Need more lookaheads.

EDIT:

lol here are big greens

19:55:30 <BigGreen> 2.07, 2.76, 2.14, 2.36, 1.78, (0.97), 2.72, 2.04, 3.20, 2.06, 1.89, (3.60) = 2.30 first block

21:50:47 <BigGreen> 5.55, 5.16, 5.37, (13.47), 5.68, 6.56, 5.72, 4.30, 4.85, (3.93), 5.67, 4.15 = 5.3 avg
21:50:50 <BigGreen> both blocks

While I was trying to figure out something else, I stumbled across this.

(L2 D' L2 D) (U L2 U' L2)

A double J-perm. Interesting, but I don't think very useful.
 
Excellent, square 1 algs were exactly what I was trying to figure out. (I'd rather figure the puzzle out for myself than follow a tutorial.)
 
Can anyone direct me to some sources to learn EOline for ZZ? I've checked some tutorials and stuff but they just confusing and dont help much. Anyone know a helpful and reliable resource?
 
Understanding the EO step of Petrus might help you understand the concept before you try to do the whole cube like that.
 
What's the second algorithm for? It doesn't seem to do anything useful.

EDIT: Nevermind. Performing it on the correct puzzle helps.
