Random Blindfold Cubing Discussion

It is an issue and you know you will have parity if you get even number of edge targets and odd number of corner targets or vice versa while memoing

How do you execute the parity? And when do you do the normal 3BLD parity? When there's an odd number of Corner targets or odd number of Edge targets?

I don't have any algorithm for that but what I would do on the top of my head if I had to solve it is:

If I have odd amount of edge targets
1. After I have done my last edge target (I execute corners first) and I have void parity I would shoot in this order to FL->LB->BR->RF->FL. So effectively move all E-slice edges an E move away from solved position
2. After that I just need to do an E-move for cube to be solved since in the 1. step I shot to 5 targets after my last normal edge targets and I had an odd number of normal edge targets --> odd+odd=even --> no normal 3x3 parity is left

If I had even number of edge targets
1. Do the same as before but instead shoot only to FL->LB->BR->RF. Now I would have had odd number of corner targets since I had even number of edges and void cube parity. In these cases I always solve UBR and UBL corner swapped for easy parity fix in the end.
2. So I would now have UBR and UBL swapped and my buffer(DF) and the edge needing to go to FL spot swapped. Then I would do M2 U L' [T-perm] L U' M2 to solve normal 3x3 parity and once again leave all E-slice edges an E move away from solved
3. Then do E-move to fix edges and void cube parity

Ta-daa

I haven't tried this myself but it should work. Just invented the method as I wrote this :D

When doing 3x3 bld and using OP whiling executing edges first then corners, should I memorize edges first or corners?

Corners first is advised. But it's up to you.
I also advise that you memo edges, memo corners, solve corners, solve edges.

It's easier for most people but it's personal preference.

I would advise memorizing corners then edges, then executing edges and finally corners - it makes solving parity easier and with practice you should be able to hold all the edge information in your audio memory just as easily.
 
This isn't exactly BLD but I think some of you might be able to answer:

Does anyone know where to find some good software to practise memory sports?
Mostly interested in digits and binary... (and cards but that I can practise with just the timer :P)

Search Memoriad :) boom

Is there any alternative software?

I can't go any higher than that.

http://www.memoriad.com/memoriadsoftware.asp
This program has binary,digits and cards. You can adjust what is highlighted, the time for the attempt, or just memorize for a certain time.

http://mt.artofmemory.com/

This site has a training section for random words and other things. It seems to be down for maintenance, but it was up this morning and should be back up soon.

http://www.memocamp.com/
This site costs money but most of the fast people use it because it has all of the events, tracks progress and does an analysis of make common mistakes are. The fun events(fun50, fun100,fun random words) are open for free. The best benefit of this site is it's names and faces.

There is a World Memory Championships group on facebook and if you go to the files button on the top of the page, there were excel spreadsheets that are used for official competition. I downloaded the 15 minute numbers file a while ago and use it for my hard copies of digit training. There is also a file for recall papers for the 1 hour cards event. The Germans made the legal recall sheet with check marks on the side so you can still use the method of elimination like what would be done in speed cards without having a second deck to reconstruct. If you don't want to use that site, then you can pm me your email and I'll send you those.

For spoken digits, I have decided that the flash digits in memoriad is just as good as spoken digits and practice with that. If you want the real thing, then I also have the official .jar file made by Florian Minges. Someone messaged it to me so I don't know where to search for the file online.

This is a random letter generator. You can also replace the letters with whatever characters that you want. It also downloads well to be used off line. I usually use this to just practice reading. I set the numbers into 5 groups of 4 and repetitively press the space bar after reading the line.

For abstract images, there is a limited amount of textures(which I have a PDF of). For names and faces, I copy and pasted a large online database of first and last names into excel. They are randomly selected to format onto a printed page and I make separate sheet with faces on it. That's very inefficient so I think it's good to just use the techniques when you meet someone.

I think that's all that I use except for qqtimer which every cuber knows.

Thanks a ton! :)

I'll definitely give these a try tomorrow :tu
I think I'll stick to digits, binary and cards for now. Maybe I'll look into spoken numbers and faces and images stuff later...

EDIT: hmm... for some reason I can't register on that memocamp site. When I fill the info and press save information/create account button it just clears everything I have written :/

Possible? Sure. You can do something like U' Rw U Rw' F' Rw U Rw' U' Rw' F Rw2 U' Rw', and then doing r or l slice turns to bring wings into position. The problem is that those algs affect 4 wings so you will need to do some tricky stuff to deal with those. r2 is probably better and easier.

OK, I was just trying to experiment since I don't use M2 for 3BLD edges...

From top profile of cube on U layer. Os are solved unaffected pieces.

Edge A and Edge B switch positions. Corner C and Corner D switch positions. Almost like a T-perm but only affecting 2 wings instead of 4 wings.

Sorry this was the easiest fix I could find...
