this week's fmc scramble seems to have got...umm.... popular?
Official 20 FMC single!
Tolong Diam Medan, round 1, solve 3
R' U' F L2 U2 F' L2 B2 F2 U2 R2 F' R F2 U F2 D R F2 D2 U F2 R' U' F
(R' U' D2 B2)//222 (4/4)
F' R' U F'//223 (4/8)
U2 B (B)//F2L-1 (3-1/10)
F' U F//3e3c (3/13)
F' R' * U F' U2 B F' ** U F B D2 U R
*=R2 U' F' U F R2//3c (6-1/18)
**=F U B U' F' U B' U' (8-6/20)
Final: F' R U' F' U F R2 U F' U2 B U B U' F' U F D2 U R (20)
F' R' * U F' U2 B F' ** U F B D2 U R
*=R2 U' F' U F R2//3c (6-1/18)
If you use Rniss at that point, the cube is an F2L-1. That insert is the optimal alg to solve the F2L pair which I learnt a while back. I saw it this way, although the setup to sexy way of viewing it is valid too, but perhaps less obvious to findWhat is that first insertion? I've never seen something like that before. I guess a better question is if this is something intuitive that I just need to think about more or is it some set alg that you have down for this very occasion?
Ah, I see... Just Set up move sexy.
???6, 4, 8
Not really an answer, but I once wrote a NISS block solver and I think it managed to solve a fixed 2×2×2 block (i.e. not colour neutral) in at most 5 moves >90% of the time. (Let me check again; don't quote me on this yet.)What's the probability of a scramble having
1. >=5 moves optimal EO (allowing NISS)
2. >=5 moves optimal 2x2x2 (allowing NISS)
3. both 1 and 2
4. neither 1 or 2
I assume finding 3 of these will give the 4th one

R2 F' R Solved the cross and create 2 pairs in 3 moves on the inverse !Why do you do R2 F' R? It literally doesn't make any pairs
and create 2 pairs
yeah that makes the most sense.Yes you have true, I can change it to R2 F' R // Cross if you want !
