I found optimal algs for all PLLs in HTM, ignoring initial "AUF's" (Macky's term: adjust-U-face).
http://cube.garron.us/algs/optimalPLL/

Of course, it was no work: just feed them into Kociemba's program.

I haven't seen a list of these before (there was a question about this, http://twistypuzzles.com/forum/viewtopic.php?t=6512, but I think that concerned execution), so I typed them up.

I found two algs particularly noteworthy:
Y: F2' U F2' U F2 U' R' U' R F2 R' U R
E(?): L U' R D2 R' U L' R U' L D2 L' U R'

I found that E perm by myself a while ago :D (it's a simple commutator).

Also, thanks for the algs, I'll have to go through them all sometime.

I found the Y perm a little while ago, although I prefer the inverse:

(R U R') B2 (R U' R') d' (R2 U R2' U R2)

I found that only the G, R and the conjugated slice-cummutated Allan are actually optimal.

What does that mean? Are you talking about a set of algs but you don't tell which set that is?

I was talking about the algs I use (and I'm sure a lot of people do).
I should probably clarify that...

qq: That Y-perm is slower than the double OLL alg one. I used to use exactly what you did, but it took me around three seconds. Now, I am sub-2 on the double-OLL Y-perm.
