World Record limit fo 3X3?

[Camilo Chapman]

Hi guys. Just wondering when you thing the world record for rubik's cube will get to it's limit.

 

[willi pilz]

3.4 feliks PB in comp.(2017)
never been beaten until 2027. Just my guess

Couple hundred years. Something sub-1.

impossible

Couple hundred years. Something sub-1.

Well gods number is 20, and the highest TPS is 12... Highest possible might be like 15. And looking/thinking takes time, I don't think sub 1 is possible.

Edit: never mind, I just realized gods number being 20 doesn't mean someone can't get a lucky case and sub-20 move solution with some crazy future method

I can get 15

(Jk, I know you mean 1.5. At least, I think so.)

does anybody know what the average optimal solution for the 3x3 is? I can't find it anywhere
I'm guessing 17 or 18 moves
But optimal solutions are harder to fingertrick so you can't spam tps

I think the absolute limit for 3x3 is sub 3 single and maybe sub 5 average

If you mean mathematical average, I have no idea. If you mean most commonly occurring, 18 is about 67%, 17 is about 28%, 19 is 3.5%, and 16 is 2.5%

Why would I mean 1.5 turns per second? That's not very much

If thats the case then on average it would be
18*.67+17*.28+19*.035+16*.025
which is 17.885

He thought you meant the total time to solve it, because 20 moves/12tps~1.5seconds

 

[Jbacboy]

Yes the world record is the limit fo 3x3

 

[One Wheel]

Sometime in the next 30 years somebody is going to come up with a reliable method of one-looking a near-optimal 3x3 solution. It won't be me, but I predict a sub-3 single and around a 4.8 average is the limit.

Theoretically, a sub-1 WR for 3x3 is feasible. The WCA regulations state that,
"An official scramble sequence must produce a random state from those that require at least 2 moves to solve (equal probability for each state)."
This means that at competitions it's possible for a scramble as low as two moves to pop up! I'm fairly certain that if a 2,3 or 4 move scramble were to be generated for a comp, people would be able to one look the solve and sub-1 for 3x3 would happen. Of course given that there are 4.3 x 10^19 possible permutations of the Rubik's cube and less than 50 000 that have an optimal solution of 4 moves or less, the probability of this happening in the next 100 years is probably less you winning the Powerball every week for the rest of your life. But hey, it's possible!

Lucas Etter has gotten a 20 tps J perm, it's on his YouTube channel.

Except TNoodle is used to generate scrambles and it throws out scrambles with short optimal lengths (<13? IIRC).
