That is incredible.Your equal to god.

Hi Tomoaki,
I was on the beach all day and now just heard this great news.
Very smart solve!
This defenitely should have happened some time
I'm glad it's you!
Congratulations.
Gus

 

[Sillas]

Congratulations!

 

[AlexByard]

Well done!

congratz. makes me want to try fmc.

Once the world record is under 20 moves, would all FMC scrambles have to have at least 1 solution that beats or ties the WR to make it fair?

Also, the longest standing WR is now square 1 single.

I'd say no, but that brings up an interesting point: eventually we may have a situation where it is mathematically impossible to beat the world record in some competitions.

Of course, this is arguably true for, say, 2x2 single as well... but FMC is an actual event.

How is 2x2x2 single not?

Agreed, but you must note that the distance for the most position of the cube (from the solved position) is 18 (http://www.cube20.org/) so the real problem will occur when the WR will be 18 (or less).

Some positions require 20 moves, such as the superflip. As it stands, in some rounds of FMC, you won't be able to beat the world record.

Some do indeed, but there are only ~3*10^8 such position out of ~4*10^19 (see the link), so practically you will never one by using a random-state scrambler. (The Cube Explorer is very good solver program, but it doesn't find an optimal solution in every case.)

It can do so easily.

"some" and "you"?

Will happen once in about 133333333333 scrambles and we've had about 400 so far.

=> I don't think he (or any of us, or cubing) will live long enough for your statement to be correct (but mainly because you mentioned 20 moves, since it'll become much more likely to happen should someone improve the record further, which is also rare, but I'm guessing not as rare as 20f* positions).

Hmm, I didn't realise that positions of depths >18 were so uncommon. (For what it's worth, Iras' wording implied that the maximum depth was 18, and that was the point I was mainly addressing.)

 

[Stefan]

Hmm, I didn't realise that positions of depths >18 were so uncommon.

We were talking about 20f*, not >18. Only 20f* positions prevent beating the current WR.

(19f* is rather common, about 1 in 29)

Pardon me, but what does NISS stand for?

Pardon me, but what does NISS stand for?

Normal Inverse Scramble Switch

Aka you switch between the given scramble and its inverse for the solution

Congrats Tomoaki san

Take a look at my Avatar I'm with a handsome Asian cuber

Congrats Tomoaki

so now FMC event is over or what?
