Void Swap: A Unique Beginner 3BLD Method

[bcube]

My working alg for this case is:

Yeah, I don´t like u moves. But maybe it is because I am not used to them at all. Thank you for the example solve.

Of course, you'd also want something for corners with the same center parity.

Oh, now I see what you probably meant - solving corners using 1 algorithm which is also swapping centers in order-2. While I was thinking of the way that is outlined in the post no. 1 - i.e. by solving corners using 1 algorithm which is not affecting centers. Well, both approaches are fine I guess (in yours parity is not considered at all, in trangium´s parity is addressed by using algoritm for edges).

I mean, your approach is a little bit easier for memorization (you don´t need to do the check for parity) but a little bit harder for algorithm execution. And vice versa for trangium´s approach.

Yeah, in my mind it's this or bust. The options for edge algs are so good on modern cubes that they're a no-brainer. If we could find a compatible corner alg even half as good, then we can eliminate the need for beginners to learn parity.

For what it's worth, if anyone wants to pick up the torch: here are my best notes so far.

Edge algs that void 2-swap U ↔ F centers:

M' u' M' u M' u M' u2' M' u M' u M' u'	UF ↔ BD	"The Sprinkler", easy to remember if you track U corners
M' (u' M' u2' M' u2' M' u') M2' (u' M' u2' M' u2' M' u')	UF ↔ DB	Neat buffer + target combo, still quite nice to execute since and learn most of it is repeated (and the repeated part has an "ABBA" pattern")
(u' M' u2' M' u2' M' u') M2' (u' M' u2' M' u2' M' u') M'	UB ↔ DF	Same edges as Pochmann M2, rotation of previous alg

Corner algs that void 2-swap U ↔ F centers:

R Uw R U2' Rw' U L D' L' F' R U F Rw' Uw' Rw U2' R2'	UBL ↔ RFD	Same corners as old Pochmann
(Uw' Rw')2 (U' D') R U R' D R2 Uw' R U (M' R') Uw2 U' Rw U	UFR ↔ URB	Same corners as T-perm
R' u2' U' r E r' u' r' U' D' R U R' D R2' u' R U M'	ULF ↔ RDB	F↔B mirror of old Pochmann
Rw2 U Rw2' F2 Uw (Rw R) U' F2' Rw2' D' (Rw R) Uw (Rw' R') (U' D)	UFR ↔ DLB	Neat buffer + target combo (ideal for right-handed), can be done regripless
U' l' U R' U' R2 x' U2 r' U' r U' . M' u' M' u M' u M' u2' M' u M' u M' u'	LFU ↔ LUB	Conjugated optimal J + the sprinkler
u M U' M u M' r F' r2' U' F U F r2 F r' u2'	URB ↔ DRF	Same corners as Pochmann R2
r2 u' r2 D2 r' u r D' r2 D r2 u' r2 u r2 D2 r' u' r D r2 u r' u' r2 D r2 u	UFR ↔ DLB	Long (28 moves)

Edge algs that void 2-swap L ↔ F centers:

u' M2' u' M' u M' u2' M u' M' u2' M' u' M' u' M'

UF ↔ DB

Corner algs that void 2-swap U ↔ B centers:

R2 F2' U' r' R' u R2 F2' u r' R' U' r R F2 U'

ULF ↔ UFR

And of course these can be mirrored and rotated in more ways, although I've tried to find the best combination of "pedadogical + ergonomic" for each one listed above.

I'm still hopeful that there's a corner alg around 22-24 moves that makes up for its length by being easy to remember and execute.
