The FMC thread

[tseitsei]

Does anyone know why you are limited to 3 cubes in FMC. Thoughts on if this should change?

So it doesn't become an arms race. Solving and rescrambling the cube takes time. Time is really valuable. So someone might bring 100 cubes if there was no limit so he/she would never have to waste time solving a cube before rescrambling it. They could just take a fresh cube. Now everyone does not have 100 cubes availible so that would give unfair advantage to those with extra cubes. Having a limit makes the event more inclusive and fair for everyone

Optimal after DR. I’m quite pleased with this solve, given it felt like a worse than average scramble. There are a few variants of this 8c8e DR, but they’re all 23 optimal. I didn’t really have much else.

This one is a bit iffy. I finished writing my solution with no seconds to spare and almost DNF’d due to bad handwriting. For some reason I missed that you could do the DR without the parallel move, so it would’ve been 9 to DR. And, since it gives a different slice, it’s solvable in +1 instead of +2. So I missed a 21 here. I’m not too mad though, since it’s very rare to have a mo3 where everything’s perfect. I’m glad I actually got sub-24 here and not DNF.

Optimal after EO. This is the star of the show. 8 moves to 1qt. I found this DR pretty early in and literally didn’t check half my EOs. There’s another DR in 8 by starting with L2 B2, and I tried 9-move extensions as well, but they weren’t better. Mallard doesn’t find better than this 20, so I found the best possible solution. Lowering my PR single from 22 to 20 feels amazing.

Overall, this 22.00 mo3 is exactly what I wanted from this competition. My practice had paid off. Even though there’s still a gap between me and wen/jay/radek/LMR/shota/etc, I have a high enough ability to win competitions against top level players and I get sub-23 mo3’s very commonly at home. I have more official FMC coming up, and to be completely honest I do not expect to beat this, but I’ll do my best.

Amazing scramble! 2 move eo and found 2 promising 10 move DRs in 20 minutes:

U B' //EO 2/10

And

At this point I decided to stop searching for DRs and use the remaining time to
try and find optimals for those 2 DRs and hope for the best.

Best part of this solve was that I was actually able to find optimal continuations for both DRs!

1st one:

This is what Ryan´s Java applet is showing (redundant cube rotation are not shown). Note that he is probably counting moves 3 and 4 as one move (the reason for this might be that they are both on the same axis).



Link outside the forum.

Edit: it is actually a 22 move solution because if cancelling moves are not considered, the solution is following:

So about the F2 in bold, this isn't a move I would normally think of doing but I just couldn't find anything good, so I did some random moves that don't affect EO or the blocks to see if that would get me anywhere, and I found F2 which would solve the cube in 9 more moves.

can someone who's actually good at fmc rate this 31 (eo + blockbuilding)


1. I looked at 2 EOs (not more because knowing me I would DNF due to time limit) and chose the better one, but they both gave 8 moves to 2x2x2 so I just chose the second one hoping for a better solution
2. Pseudo 2x2x3 bc why not, I also had a choice on F2L-1 between two variations of the same goal, I chose the one that makes a block to give me 5c
3. Making a real effort to find good insertions, I was able to cancel 5 moves in total giving me a 31

 

[CornerTwisted]

Now everyone does not have 100 cubes availible so that would give unfair advantage to those with extra cubes. Having a limit makes the event more inclusive and fair for everyone

Technically wouldn't 3 be leaving people with less cubes at a disadvantage? And realistically shaving off like 10 seconds every time after the third you scramble wouldn't be entirely detrimental.

If that's your entire working paper, check like maybe 4 times as many things.

Also extending 222 to 223 can be done in three directions, but if you have EO already done, then only one of the directions is "good" (the two free faces don't break EO) and the other two directions are "bad" (one of the two free faces will break EO). It's not necessarily a bad idea to extend in the "wrong" direction, especially since sometimes that's the only reasonable option you have, but it's significantly harder to work with.

Also also, your skeleton is 20 to 5c, not 19 to 5c.
