There are two notations for 15 puzzle rn. You can track which piece is moving into the empty spot (using U, D, L and R to denote the direction), or you can follow where the empty spot is moving in the same way. I also see on csTimer that they added an option where it shows the direction to move...
4a is 8 algs and 4b is 15, so it's actually not that bad. I may have worded myself poorly (which is something I do often), but you're solving F2L so that there is a solid face on the bottom that needs to be permuted. The main advantage of this method is that EOcross is much easier to solve in...
This probably already exists, but I think it's cool.
1. EOcross, but the edges can be permuted in any way
2. F2L-1 (kind of), solving edges into their correct location, but putting corners wherever is easiest
3. Solve the last pair and orient the LL corners (probably with WV)
4a. Permute corners...
I've been thinking about doing this recently. I know full EG and was considering learning NLL for cases with really bad faces but good opposites. I've decided to learn LEG instead (which is the smarter thing to do), but might learn NLL someday. These are the algs for HD...
Use Ortega or learn CLL. COLLs are much worse than CLLs on 2x2. I honestly recommend you just learn CLL if you care about 2x2 since you already know some of the algs and the rest are super easy.
- Use good algs
- Prioritize layers over faces
- Build efficient faces
- Plan your face in inspection
- Build your faces so that the bar is in the front (or back depending on which alg you use)
- Plan oll in inspection on easy faces
- Turn fast
- Practice
Or you can just learn CLL
Yeah, I was worried that most of the algs would be garbage. So far only about 7 of my R2 U2 R2 U2 R2 algs are any good. I'll try making algs for the whole set, but chances are they'll be much slower then CMLL (then again, I probably don't have the best judgement on what's good and I'm not...
I like the idea of solving SB in one of six ways, but it would make CMLL + SB have a ton of algorithms (43 x 5 = 216 (excluding CMLL)). Maybe since the 2G algs are by far the best one I've genned so far, doing CPFB would be useful? that would bring it down to 40 algs, which is super reasonable imo.
