2x2 OO Thread

[CubeLite]

Can I submit solutions that has a bigger movecount than the one that they provide, so like the inverse of the scramble is 9 moves, can I submit one with 10 moves?

OO is a resource to compile an optimal(not by movecount, but how fast you can execute it) algorithm for every possible 2x2 state. If you want to learn it as a method, you would have to learn over 154k algs(a 2x2 has 3.6 million combinations but some of them are just the same state with different colours).

I’m not gonna learn that lol but good luck on the development of this method!

If it is easyer to fingertrick, i think yeah

It had 3 F2s, but it says that it doesn't matter the orientation, so it could be better, with like 3 U2s

Wait, sorry if I sound dumb, but is OO a method? If so, is it easy to learn?

It’s learning 150k algs. Not sure if it’s that easy…

2. Also show previous submissions which have not yet been approved, so you can be sure your work isn't overkill.
Both of these seem like they would limit the number of redundant submissions made on the website, making it so that the top 2x2-ers only have to check relevant submissions.

Let’s analyze this comment together, as it is probably the only negative response I have seen to this OO movement in general, and it raises a couple of valid points, which shouldn’t be ignored as legit concerns



This is an opening sentence to an argument of all time. The “everyone’s time” is an obvious hyperbole, but aside from that, this sentence is subjective, and I can’t say that this opinion is completely incorrect. One last thing is that clarification to what better “ways to go” is not given, which could definitely be clarified easily

This is the most interesting thing in this comment, as it shows and lays out @abunickabhi’s most powerful and personal argument; UF5. Throughout the rest of this comment, he references this from his personal experience to gen, plan, and attempt to make a method to solve 5 edges with one alg. For whatever reasons that may be, top BLDers mostly dismissed this method as a waste of time, as the algorithms are seen as too unfriendly for finger tricks, as well as the tens of thousands of algs needed to learn it.

I feel somewhat conflicted over this opinion in particular, as while I can somewhat acknowledge that top solvers have more representation in the cubing scene in general compared to regular and even good solvers, this type of phenomenon that @abunickabhi is referencing is very common is speed cubing, as method innovation is practically always led by the fastest solvers who have learned everything before them (that is just how solving progresses over time)

Finally, we come to @abunickabhi’s last point; because genning and organizing OO algs is a lot of work, it will never be viable. This is more of a prediction, so I would not like to delve to deeply in making a counter-prediction which could make me look a fool in a couple years. However, I will note that so far, the OO movement has what @abunickabhi has not had for whatever reasons; multiple people. And it’s not just two or three people; there are dozens of people who have been solution hunting, not just including world class solvers (lol me). Whether every single OO will learned by a single person is unclear, but if some -3 year old Chinese prodigy decided to start learning algs early, this resource will be there

Thanks for clarifying a lot of my doubts!

Yes but please don't submit stuff that isn't objectively optimal, I'm not submitting anything because I'm not competent at 2x2, if you can't sub-1 the scramble then it's not objectively optimal and if you can't sub-1 a 10 move solution on stackmat then don't bother submitting anything (like me)

I also only submit solutions that I can sub 1 (avging 1.3)

Tip: try to find an efficient solution or take one of the optimal sols and find the best angle to do it from

I use the 2x2 sheet to find algs btw, and maybe try to cancel some moves

My fingers are still recovering, so I can't see if the scramble is sub 1

This is cool, I quite like it. I'll probably spend more time on this website than I can afford lol

There are two things which I think would be very valuable additions to the website:
1. Check if a submission actually solves the cube. I accidentally submitted something that wasn't correct, and it went through without problem.
2. Also show previous submissions which have not yet been approved, so you can be sure your work isn't overkill.
Both of these seem like they would limit the number of redundant submissions made on the website, making it so that the top 2x2-ers only have to check relevant submissions.

Yes, I agree with both, especially 2, as the first "solution" I sent was, "fugb"

There is an actual real debate going on to change OO to UNG or Under Normal Gambit

Ima make a poll

since people are getting so good at 2x2, I feel like corners first methods could be viable on 3x3

I was actually doing CF solves the other day and was averaging about 15
