Silly 3x3x3 Speedsolving Challenge

[Zane_C]

This was bad, me trying to use the optimal solutions slowed me right down and turned many of the times like normal solves. I didn't once find the optimal solution, however the 6.87 came close I think.

18.99, 24.78+, 18.89, (DNF), (6.87), 11.92, 20.21, 17.17, 18.80, 29.96, 19.47, 16.93 = 19.71

Now do:
(Scramble) -> (Cube explorer solution minus number of turns you want your scrambled state to be)

This will give a long scrambling alg, but it does not let you know any information about the solve when inspecting.

It does let you know information even *before* inspecting: The probably optimal solution will be in or biased towards <U,D,L2,R2,F2,B2>. Might be ok if you let it solve it *optimally*, though that takes long and there still might be a bias.

Better:

1. Take random 25-mover: R' D2 B' R2 D R2 B2 U' D R' U R D L2 U B L R2 B' R2 D2 F B' D2 U'
2. Let Cube Explorer solve it: L2 D' L2 U' B R U' B' U' L' F R U' L' D' L2 U' F2 D2
3. Concatenate but leave out the first few moves of the 25-mover scramble:
   B2 U' D R' U R D L2 U B L R2 B' R2 D2 F B' D2 U' - L2 D' L2 U' B R U' B' U' L' F R U' L' D' L2 U' F2 D2

Well, this still lets you know that the solution doesn't start with the first scramble side (B here). Might want to leave out one fewer move (just 5, not 6) and modify the next, e.g.:
R' B2 U' D R' U R D L2 U B L R2 B' R2 D2 F B' D2 U' - L2 D' L2 U' B R U' B' U' L' F R U' L' D' L2 U' F2 D2
Of course now you know that the solution *does* start with the first scramble side. Ideally there'd be no connection so the solution should start with the same side as the scramble 1/6 of the time. So use the first way 5/6 of the time and the second way 1/6 of the time. This works for you generating scrambles for others, but to protect everyone including yourself from the knowledge, a program should do it.

29.99 31.34 38.13 30.60 26.66 (48.33) 27.83 30.36 36.87 (26.21) 32.79 28.31

Average of 12: 31.29
Session Average: 32.29
Best Rolling Average of 5: 29.60

This is perhaps 2-3 seconds below my current average... and you would think surely that I would have beaten my PB non-lucky single with one of these scrambles, but I was actually 3 seconds away from doing so. That is kind of disheartening really.

1. 48.58 - normal solve
2. 29.61 - normal
3. 37.10
4. 58.34
5. 26.05
6. 46.49
7. 1:14.46
8. 1:02.31
9. 31.02
10. 25.29
11. 17.28
12. 48.82

Never found the optimal solution or even close. Certainly not my game I'm not very good at block building, and that certainly helps in this exercise. All were normal solves, though 11 was especially easy with a 3XCross or something.

2.50, (10.28), 1.58, 2.33, 9.73, 1.42, 9.31, (1.38), 4.39, 9.16, 1.53, 2.11 = 4.41
Seems like a pretty good average

 

[Rinfiyks]

Better:

1. Take random 25-mover: R' D2 B' R2 D R2 B2 U' D R' U R D L2 U B L R2 B' R2 D2 F B' D2 U'
2. Let Cube Explorer solve it: L2 D' L2 U' B R U' B' U' L' F R U' L' D' L2 U' F2 D2
3. Concatenate but leave out the first few moves of the 25-mover scramble:
   B2 U' D R' U R D L2 U B L R2 B' R2 D2 F B' D2 U' - L2 D' L2 U' B R U' B' U' L' F R U' L' D' L2 U' F2 D2

Better still, get someone else to just input the 6 moves

Wow, Ville, that's amazing! So why are you so good at this? Is it because of your BLD inspection practice? It seems like you're disproportionately better at this than most of the other really fast solvers. (Well, I guess plechoss was pretty amazing too!)

Found quite a few optimals... Couldn't be bothered to try when I didn't lol.

All the 2s are optimal, most of the rest were easy blocks. The 1:03 was a pop...then again, I was already at 26 when I popped =)
