Weekly competition 2007-43 (2,3,3OH,4,5,BF,SQ1,MG,MMG,FMC,MM,PM,Relay)

[hdskull]

I believe the generally accept practice is two layers for scrambling, and just the inner slice when it's in an algorithm.

Really? I scramble the inner slice only, hmm... I'll check the WCA scramble later.

 

[masterofthebass]

On the WCA scrambler, there are 2 options: Multi-slice and not. Multi-slice provides a way easier way to scramble, and is mostly used for competions. For these competitions we use multi-slice, but if you really want to you could do inner only scrambling.

No, you will get disqualified for using inner slices only for this competition; it yields a different scramble.

All bad.

Fewest moves: 29 moves
scramble: U' R D' L' U L D R B F2 L' U L D2 F' U2 B' U2 (18)
My solve: F2 L2 B' D F R D U F2 U'B U' F' U2 F R U2 R' B2 D' R2 D B2 L2 D F2 D' L2 U (29)
explanation:

cross + pair: F2 U'B
F2L: U' F' U2 F R U2 R'
LL: B2 D' R2 D B2 L2 D F2 D' L2 U

Also found very nice start on inverse scramble: U2 B U2 F D2 L' U' L F2 B' R' D' L' U' L D R' U
D L D2 R' F' L U' D2 F2 U2 but found no good continuation within the remianing time.
Can someone finish it in 28 moves or less?

oh i see, thanks

 

[AvGalen]

I really, really, really swear I found my Fewest Moves solution myself, but is is equal to Guus. If anyone believes I didn't find this myself I can send him my notes via email. I am wondering if this has ever happened before:

2x2x2: 9.86 10.93 10.81 10.15 7.19 = 10.27
3x3x3: 22.21 25.94 27.93 24.81 26.80 = 25.85
3x3x3_oh: 55.05 49.40 55.33 1:05.47 50.09 = 53.49
4x4x4: 1:48.58(P) 1:33.38(O) 1:58.09(O) 1:39.96(() 1:51.34(OP) = 1:46.63
5x5x5: 2:54.78 2:54.63 2:43.63 2:33.71 2:39.36 = 2:45.87
2x2x2_bf: DNF, 2:21.09 = 2:21.09
3x3x3_bf: DNF, DNF = DNF
Relay: 6:01.15
Square-1: 1:31.13 1:33.97 1:46.03(P) 1:36.91(P) 2:18.19 = 1:38.97
Magic: 1.81 1.81 1.78 46.41 2.81 = 2.14
Master Magic: 5.97 10.97 5.61 6.06 8.03 = 6.69
MegaMinx: 4:09.56 4:03.19 3:42.81 3:15.97 3:23.46 = 3:43.15
PyraMinx: 23.08 16.09 15.43 25.86 15.33 = 18.20
Fewest Moves: 29
F2 L2 B' D F R D U F2 U' B U' F' U2 F R U2 R' B2 U' B2 D L2 F2 U F2 D' L2 U
Build a 1x2x2 + 1x2x1 + 3rd pair: F2 L2
Build a 1x1x3: B' D F
Connect the 1x2x2 + 1x2x1 to form a 1x2x3: R D
Cross+3rd pair: U F2
Finish the 2x2x3 to form a triple X-cross: U' B
4th pair + OLL: U' F' U2 F R U2 R'
PLL: B2 U' B2 D L2 F2 U F2 D' L2 U

Guus: We really should start doing team-fmc. Not only do we think alike, but I can improve your solutions, just like you can improve mine. It took me 5 minutes to find this solution, including the cancellations

Also found very nice start on inverse scramble: U2 B U2 F D2 L' U' L F2 B' R' D' L' U' L D R' U
D L D2 R' F' L U' D2 F2 U2 but found no good continuation within the remianing time.
Can someone finish it in 28 moves or less?

You shouldn't have created those 2 pairs with the 8th move (D2) If I make a slight variation of it I can get a good result (do premove U2 to see what is going on)
D L D2 R' F' L U' F2 U2 (your 2x2x3 block, but with only 1 pair saved)
B' D' R' B R (cross + 3rd pair + last layer nicely aligned)
D B D B' D (finish last layer except for corner 3-cycle. 3 move cancellations with next moves)
D' B' U' B D B' U B U2
And you can probably find a shorter corner 3-cycle insertion.

So the solution based on the original scramble would become:
25: U2 B' U' B D' B' U B2 D' B' D' R' B' R D B U2 F2 U L' F R D2 L' D'

 

[hdskull]

I redid 4x4x4 because I scrambled wrong.

4x4x4: 2:08.62, 2:12.11 O, (2:17.95 OP), (1:48.75 P), 2:11.12 OP => 2:10.62

On the Last solve I was done with 3x3x3 F2L at 1:27, OLL parity and PLL parity took me forever.

I taught them how to do Arnaud's Magic flipping-only method this weekend, and they had a great time playing with the Magic and Master Magic. Their times have already improved greatly since these times here - these were done very shortly after they learned how.

I spent too long finding a good start so I ended up with a bad finish.

Woooooow Arnaud, indeed we are the best FMC-team. 25 moves is far beyond the world record. I think there is no shorter corner-insertion, canceling out 3 moves is very good. I'm just wondering how I could have missed that solution, I'm sure I tried F2 U2 after move 7.

I do believe you found you 29-mover independently because it is a very straightforward one, although it took me 40 minutes to find, replay, write down, triple(!) check etc. And you found it in 5 minutes?

Well, have a lot of fun in Sweden but don't push yourself to hard at the FMC (ha-ha)

See you

Hi Guus/Gus,
Sorry for the misunderstanding about the 5 minutes. I didn't write that down clearly.
I spent about 30 minutes finding the triple X-Cross on the regular scramble. Finding the 2x2x3 block took 2 minutes and then I just kept on improving it (less moves, better continuations) untill I found the triple X-Cross. I needed 10 minutes to do the 4th pair + OLL and 10 minutes to find the T-perm in my memory. I was very lucky to know this one because Clement Gallet told me at the Polish Open and it is really easy to remember: (B2 U' B2 D) L2 (F2 U F2 D') L2 U
The 5 minutes I mentioned was how long it took me to find the solution based on your inverse-scramble start. My first attempt used your 2 pairs (no good continuation). My second attempt used my alternative start and I found this continuation immediately. If you really tried that alternative start I don't understand how you could have missed that one. Everything fit together automatically, even the corner 3-cycle at the end.

At the Swedish Open I will make sure not to DNF and I am aiming for sub-35 (but I will try to get the WR if you don't mind)

Hmm, i thought you are also the only team As i predicted earlier the 28 can be beaten comfortably with a nice scramble and some luck, by avoiding mistakes and other waste of time. And there's a number of people who can do it now. And with the increasing number of competitions it will surely happen in 2008. I can almost guarantee this

Arnaud, this has happened to you at competitions too. What happens on your really slow Magic solves? Does it come apart and you have to restring it? Just curious.

A nice scramble would help
Some luck is always good
But I really believe sub-30 is possible on almost any scramble. This record is long overdue to be broken.
I wouldn't mind breaking it next weekend though. Then you can break it next year

And yes Mike. In this case a string actually came loose. I put it back together, solved it (it was a little scrambled) to a flat state and then finished it. I just refuse to DNF.

 

[mrCage]

But I really believe sub-30 is possible on almost any scramble. This record is long overdue to be broken.

Sub 30 is of course always possible (optimal solver). And probably always possible by humans (skeleton + insertions). The hard part is the 60 mins limit. For that reason i'd say low 30's is always possible by humans when avoiding silly mistakes.

If you break the record this weekend i'll do my best to beat it later ;-)
