Random Cubing Discussion

Jarcs is just another rubiks cube solver. It's an online solver that can also do cool stuff like find optimal crosses, eolines, 1x2x3's and 2x2x2's blocks.

Hey. Anybody have opinions on an MGLS-type almost intuitive alternative to orienting LL while inserting last pair? ...I guess I would say more intuitively forcing OLL skips?

I came up with something yesterday. (lets say your F2L slot is on your FR.) When you get to your fourth pair, connect them but leave them on the U face. Make sure there's an oriented edge next to it, making a 1x2x2 block. (occupying UR, UBL, and UB) You then look at the orientation of the yellow edge stuck in your F2l slot (at FR, whether yellow is facing you or facing right).
If it's facing you, rotate U so that an oriented edge is on UR. Slice the F2l-slot edge up to that, and then turn U to another misoriented edge and bring that one down into the slot, and repeat. If the rest of the edges are oriented on U, just slice your target edge up top, and bring down your F2l pair.

The thing is, as I've been doing that, I've found some intuitive cases that also orient the corners if you do it right.


Just a rant. Anyone understand what i'm getting at? I'll throw up a video later.
 
I am confused about what to call it now, but look up RLS or RV for Rowe variation. He has a webpage with every OLL skip while inserting the last pair. I know it isn't completly intuitive, but you can get Alot of ideas from his list and can notice parts of OLL's and other algs/insertions that make understanding them easier.

I think it stoped being RLS when RLS was found to also mean Repetitive leg syndrome.(off topic)

Thank you! I wonder if anybody has an extension that integrates edge orientation as well. Or a subset of connecting last F2L pair and positioning them for WV...
 
Does anyone have experience with planning cross + f2l edge piece orientation during inspection?

EDIT: After 2000 trials, optimal solutions seem to add ~1.7 moves average vs. cross alone. (With fixed cross and fixed orientation). Compared to ~1.54 extra for xcross. For whatever that's worth. (That does make think of another question: Any interesting counterexamples to the idea that goals with similar average optimal move counts would be approximately equally hard to do optimally?)
