Weekly competition 2008-05

FMC Solution (1hour):
B R' F2 D2 L R U' B U' L2 D2 L F' D' F D' L' D' L D' B R D2 R' D' B' ==> 26 moves
Explanation:
B . F2 D2 L R U' B U' does a promising ps2x2x3 block which gave me a 30 move solution in 10 minutes and 29 moves in 30 minutes. Then tried variations on the first moves and I tried R, R2 or R' inserting at the dot (after the first move). With insertion R' and continuing with L2 D2 L F' D' F I was left with a very promising last pair. After doing my 50-ways-to-insert-a-last-pair-search I found D' L' D' L D' B R D2 R' D' B', a beautiful LL-skip and 26 moves. 10 minutes were left to perform a triple check!!

Congratulations Per with you 24-mover, the best 1-hour solve you ever did? And Arnaud of course very well done with your 27-move solution. The Benelux open will be exciting! But Arnaud, never, never yell to me what you found in 15 moves during an offical FMC competition!

L2 R U2 F L' D2 L' F D' B' D2 L' F' L F D F2 L D L' D' F U' (24)

Very late entry this week. I was inspired by good entries this week to have a go. First i found B L' F2 U2 F' D2 R2 F, making the same 2x2x3 block as found by Mike. However nothing good came came out of it after studying it for 20 minutes. I then found a longer block L2 R U2 F L' D2 L' F D' B' which showed promise for a good finish. With only a few minutes left i cracked it :cool:

Btw, very nice insertion Arnaud. I found one more 27 solution from that start with slightly different insertion, and a 28-er with 2 insertions;) (block + corners)

Hi Per,

Your solutions doesn't solve the cube, I think one move is missing because you entered 23 moves without explaining the last steps. Which one is missing?

This is just mean :) So if I had waited with posting my solution you wouldn't have competed? That is good to know for next week ;)

You are simply to good for me Per. That 27 was already a crazy good solution for me. I don't think I would have found that 8 move "insertion/commutator/lastlayer" in an actual competition. I just got lucky playing around with the pairs

And Guus beat me too :(

I promise not to yell, unless I break the world record Guus. But to be fair, you told me you found a 33 move solution after 10 minutes (when I was still searching for a good 2x2x3 block)

Hi :-)

Yes i believe it's the best 1 hr solution i have done. My best lienar solve is 28 in 1 hr. My best semi-linear (taking back moves allowed) is 24 also - done 20+ yrs ago. And finally my best FMC (unlimited time) is 19 turns only. Check Dan Harris' challenge #102!! I will check to see if i had forgotten a turn when writing it down. I verified it with the companion so it sounds odd .... hmmm ....

Hi :-)

One turn got lost in my post editing last night - correct solution should be: L2 R U2 F L' D2 L' F D' B' U D2 L' F' L F D F2 L D L' D' F U' (turn 11 - U - was missing). I guess that disqualifies me (DNF) ???

Per,

Strictly taken checking your solution against a computer program is not allowed, like real competitions. But I have to confess I computer-check everytime before I post a solution to this forum, so I would say, no you're not disqualified but win this round. What does Arnaud think?

Arnaud thinks you are both disqualified and the next best (me, me, me) wins :D

Seriously, as long as you correct it before the deadline I don't really care.
 
Hi :-)

But in this case i had to be reminded, so i guess im DQ anyhow :-) Still happy with the solve. Next time i check the algo already typed in the webpage in the companion, not the other way round :-P Errors may happen when copying/editing the verified correct solution - huhu ;-)

(edit)
Ryan's site has a built in applet solution verifier, very handy!!

If I have the time I update the Fewest Moves in the second post of the competition, marking wrong solutions in red. As long as you don't spend over an hour and have a correct solution in your last result-post it is going to be valid. This is not an official competition where the judges need to be very strict. This competition is all about fun
 
I think that's nice of you, Arnaud, and I think it's a good rule, but for sure if your only mistake is in typing in the post (meaning you got it right on paper - which is what you would have shown to the judge in a real competition anyway; you're not allowed to type in competition - and then typed it in wrong here), then clearly it shouldn't be a disqualification. That's what Per seems to have done. I also had the same problem this week - my solution was correct on paper, but I left out a ' when I typed it in here. So I edited it and didn't consider myself disqualified.
 
it is the first time that i did the weekly competition. hope i m aloud to post my times.
3x3: (27,30) (34,65) (39,63) (31,08) (32,88) avg: 32,87
4x4: (2:48,31) (3:18,77) (3:19,58) (2:44,15) (3:22,06)
the 4th time was actually a DNF because i missed the parity so i used it as my worse time avg: 3:20,14
Magic: (7,80) (7,80) (6,46) (6,36) (6,38) avg: 6,88 did it the first time today
Relay: 12:46,71 the 5x5 took me 8 min the 4x4 around 4 min the 2x2 around 25 sec and around 40sec

Hi :-)

Well i DO consider it a DNF myself because i had to be reminded (by Guus) that what i submitted was incorrect. If i had spotted it myself it's another matter - except it was a rather late entry :-)

- Per

PS! I WILL submit FMC this week, regardless of what will be posted by others ;-)

3x3x3 BLD: 2:35.86, 2:40.53, 3:39.20 => 2:35.86
Dunno why, but just couldn’t memorize on the 3rd solve, haha.
(memo times: 1:13, 1:14, 2:05)
3x3x3 OH: 25.14, (26.42), 24.83, (24.66), 25.78 => 25.25

3x3x3 FMC: (38)
Scramble: R2 D2 R2 B' D L' R U' L B2 R2 B' D F
Explanation: B’ D2 R’ F2 B D’ B2 D2 B’ x2 B U2 B2 U’ B R' B D F U’ F’ U F B U’ B2 R B2 L’ B L B2 R’ U2 F2 U L R’ F2 R L’ U F2 (38)
Cross + 1st pair: B’ D2 R’ F2 B D’ B2 D2 B’ (9)
2nd pair: x2 B U2 B2 U’ B (14)
3rd pair: U’ F’ U F (18)
4th pair: B U’ B2 R [B R’] (22) [R’ cancels and B combines with B2]
OLL: B2 L’ B L B2 R’ (28)

I found quite a few ways to insert the last pair (4), but ran out of time to try all of them out. pretty happy with 38 moves.
