Optimal OLL maneuvers

[Bruce MacKenzie]

I am working on an optimal solver which can do partial solves--solves where some cubies are solved just for orientation, just for position or with no restrictions at all. Using this I have optimally solved the 57 non-trivial OLL cases. The orientations of the flip/twist patterns are determined by how my program does the C4 symmetry reduction and in most cases are rotated about the up-down axis from that in the Wiki database here. The configurations are given as facelet permutations of the identity permutation:

UF UR UB UL DF DR DB DL FR FL BR BL UFR URB UBL ULF DRF DFL DLB DBR

So, the first pattern listed has the up-back and up-left edges flipped, the up-front-right corner twisted CW and the up-left-back corner twisted CCW.

Question: In the listing of the OLL maneuvers in the Wiki database here, which faces are visible in the graphic--the Up,Left,Front faces or the Up,Front,Right faces?

 

[ProStar]

If you're trying to find the optimal solution for the OLLs, then you probably shouldn't. Just because an alg is short doesn't mean it's better. Take, for example, two U-Perms. Here are two algs, both solving the Ua-Perm:

R U' R U R U R U' R' U' R2
F2 U L R' F2 L' R U F2

The latter is shorter, but it will take much longer. This is because things like F2 and B2 cause you to change your grip on the cube, while during R and U sequences you can stay in the same grip, making it faster. Whenever you try a new alg, make sure you can do it quickly, with as little regrips as possible.

But if your doing FMC its very useful to have optimal algs. They never said this was for speed.

Yes, it's better to have fast algs for speedsolving, using your example @ProStar, I use the U perm that involves M moves. But, @Etotheipi is also right in that you need shorter algs for FMC, it doesn't matter how easy they are to execute. It all just depends on what you are using it for. Out of curiosity, what are you using it for @Bruce MacKenzie?

I understand. I'm not a speed solver. My interest is in the mathematics and computer cubing. In fact I don't even have a physical cube any more. A partial solver grabbed my interest as an intriguing computer problem. I put the results up here. You speed solvers can do with it what you please.

But if your doing FMC its very useful to have optimal algs. They never said this was for speed.

What is "FMC"?

 

[ProStar]

What is "FMC"?

"Fewest Moves Challenge". You have 1 hour to come up with the most efficient solve possible.

 

[WoowyBaby]

Just saying, nobody ever uses OLL for FMC. Lmao. It’s pretty inefficient, and in fact, a good FMCer rarely ever uses any pre-made algorithms like ZBLL and such. If an FMCer gets an easy F2L so now is at last layer, they wouldn’t do OLL, they’d do an AUF to get 3c3e or something like that remaining and do insertions for those cycles. I’m not trying to be mean or anything, I’m only saying that algs aren’t used in FM.

True, but for our new event speed FMC on the weekly forum competition, OLL can be pretty useful for average level FMCers like me, so it's certainly useful there!

I am aware of that lol, but as Mike said, for low level FMCers it can be useful.
