Blindsolving Discussion and Help

AbstractAlg said:
today I did few solves actually (I almost never do actual solves, only memo/execution practice).

and I've tried memo rush. I was disappointed when I discovered that my very fastest memo was around 31 seconds.
while doing memo it seems to me like I did it in ~15secs, then I look timer and it says: ~43. Whatthe?!

what is wrong with my memo?

I do memo without callback before solve, so straight forward, I recognize pieces well and convert them to corresponding letter very quickly, corners are also fine...

Time how long it takes you to trace through the cycles without memorising anything.

first ten scrambles:
19.67, 18.68, 18.52, (19.99), 15.56, 15.83, 16.31, 15.63, 18.49, (15.32)

Bad? ':|

25 more:
(18.38), 14.93, 14.62, 16.90, 15.41, 16.40, 12.56, 12.64, 16.16, 12.16, 12.12, 17.43, 14.69, 14.11, 15.57, (11.21), 13.53, 13.31, 14.26, 12.87, 13.63, 12.56, 14.62, 11.37, 12.72

sub10 seems impossible.

did three solve: 1:23, 1:32 and new PB - 1:16 [29.4x]. this tracking practice improved me memo quite a lot. thx. :)

I've only seen your and Ryan Reese's times for this, and you're both at about the same speed (for memo, solving and this tracing) so I'd say that's about normal for your memo speed. For me, I haven't done this much but I think that my memo time and tracing time are almost the same, which is not surprising to me because my memorisation has almost "evolved" from sentences to audio, and I know my letters and words extremely well.

I can't think of any advice for how to improve but it seems like you're taking about 20-25 seconds to think of the letters, form words/images and put them into memory. You might be able to improve this by practising your memorisation more, and maybe studying your word/image list more.

If you want to, you can try tracing again but saying the letters in your head without memorising them. This might give you an idea about how well you know your letter scheme. You could also do it again, but saying the word/image in your head without putting it into a sentence/journey, and this would give you an idea about how well you know your list, and by comparing this to your full memo time would give an idea about how fast you put the info into memory.

As for improving tracing speed, I think this can only be done by practising.

By the way, I think it's best to practise doing full solves instead of only memo, because this can cause you to not memorise properly and not be able to recall easily. This happened to me when I was doing BLD sim solves. If I finished memorising and didn't like it, I would just get a new scramble. When I tried doing real 3bld, I just couldn't focus and got really annoyed with it.
 
Ok, just watched Daniel Sheppard's 4BLD tutorial. I get commutators now, except the opposite centers switch (for example, white, green, and yellow) and the interchangable opposite centers (for example, white and yellow). Can someone help me out with those cases?

Also for 4BLD, what order do you do centers, edges, and corners? I was thinking centers, edges, then corners.

My current noob-tactics (assuming solving in wca orientation)
white, green, and yellow - I just use a set up move to bring the yellow center onto a side face (in this case my preference blue for a d2 exchange) and apply a simple 8 mover

white and yellow - same stuff

I need to put some more work into this :)
You should also check some example solves:
Mike's thread

Chris on Yahoo (can't find it right now...)

My order: centers - edges - corners
centers before corners allows you to use corners algs that rotate centers (like Y and J for OP corners)

I understood everything in Daniel Sheppard's 4BLD tutorial except one thing : Corner parity using OP. Assuming I want to solve corners first, I understand that I would need to turn my U face to fix the centers according to how many Y-Perms I did. Would I then have to solve centers before edges? How would I deal with an odd number of Y-Perms? The UB and UL edges would be off.

Every Y-Perm, J-Perm and L-Perm you do does a U' to the centres on the U face. Every Ra-Perm you do does a U to the U face.

For example, if you have a standard 7 corner cycle, so no new cycles and every corner just needs to be cycled 1 place onward. You will have done 7U'. Now, you need to fix the UL and UB edges so you apply the Ra-Perm to fix those and swap the UBR and UFR corners. This does a U to the centres on the U face so now you have done a total of 6U' to the centres. This means that the U face will be a U2 out from how you memorised them. So after you finish executing corners and move onto centres, you will do a U2, solve all your centres, then after executing centres you do another U2. However, because you had parity, when you've finished executing your edges you will have the corners UBR and UFR swapped. I just do a T-Perm, then a y rotation and do PLL parity and your cube is fixed.

So a few examples:

0, 4, 8, 12, 16 etc Corner Targets: You will have done 4U', 8U', etc to the cube so your centres will be exactly as you memorised them and you will have no parity.
1, 5, 9, 13, 17 etc Corner Targets: You will have done 5U' + U, 9U' + U, etc to the cube. Due to the Y-Perms and an Ra-Perm at the end. Your centres will be as you memorised them but you will have corner parity.
2, 6, 10, 14, 19 etc Corner Targets: You will have done 2U', 6U', etc to the cube. Your centres will be a U2 out and you will have no corner parity.
3, 7, 11, 15 etc Corner Targets: You will have done 3U' + U, 6U' + U, etc to the cube. Due to the Y-Perms and an Ra-Perm at the end. Your centres will be a U2 out and you will have corner parity.

I hope this makes sense. Commutators and corner twists do not affect any centres, so if you throw in A-Perms, simple commutators or corner twists (such as RUR'U'RUR'U'L'URU'R'URU'R'L), remember that only your adjacent edge PLLs affect your U face.
 
That makes more sense. I've never used R perms for parity before (OP+M2 on 3x3). I guess I'll see if I really understand it when I have my first attempt at 4BLD next Saturday. Until then I'll be working on a lettering scheme for memo. :D Thanks!
 
If im using M2 for egdes, and during inspection i notice my buffer piece is flipped, what do i do? I know you can use M U M U M U2 M' U M' U M' U2 to swap 2 opposite edges' orientations. But if i were to do this at the end of the solve, which piece would i end up swapping, because its the only flipped edge?

You just instantly break into a new cycle. Assuming there are no other flipped edges on the cube it will be solved at the end.
 
I am new to this forum I, but have been reading Speedsolving for a while now. I what to know how to solve 4x4 blindfolded, but I don't know where to find information about center comms or algorithm lists for the centers. I know how how to solve the rubiks cube blindfolded with turbo/comms(mostly just turbo for corners) and commutator notation. Can someone please help me figure out how to solve the centers.

Thank you so much. that video does a very good job explaning the things that were confusing me. With some practice, i think i can finally get a big blindsolve.
 
Would it be a good idea to memo using pokemon? There is 649 pokemon and a total of 529 different letter pairs excluding double letter pairs, Z, and Y/X depending on your preference. Some of them would be similar but I am sure I could make a system with almost only pokemon and there attacks.

I think I would get good this way and it would be a great way for anyone who grew up on pokemon which is a lot of people.

Example would be:

LDTBVN-SLABOD

LanDorus uses Thunder Bolt on VaNillite. SoLosis uses ABsorb on ODish.

Then for corners I would still do audio but I still think this could be a very good way to memo.
