ZBLL trainer

[Roman]

I've used your trainer for a while now, but since today, I've had this warning message with firefox: An error occurred during a connection to bestsiteever.ru. The OCSP response does not include a status for the certificate being verified. Error code: MOZILLA_PKIX_ERROR_OCSP_RESPONSE_FOR_CERT_MISSING

If there's a way for you to fix it, that would be great. Otherwise I'm gonna have to resort to something else.

Hey. Thanks for the report! Can you check if it is fixed now?

 

[PapaSmurf]

It is! Thanks! Now back to the L grind.

Issue with short / 2gen / stupid scrambles is now fixed.

2-gen scrambles listed here were removed from scrambles list. They were replaced by a bunch of alternative algs found on birdflu website. Short (12- moves) scrambles were also replaced.

The scramble generator tends to give you less B moves now.

[Pyjam]

Very well. Thanks a lot for this improvement.

 

[Hazel]

Awesome, thanks for doing this
I'm still going to continue working on my own trainer, partially because there's a bunch of other features I plan on implementing, and partially because it's a bit too late now to turn back xD
Neither of us are earning any money from these so I wouldn't call it a "competitor" though haha.

Thanks for the help, but I would like the scrambles. I had previously found that website. Please let know if you find another one! Thanks.

Have you tried jperm.net

 

[PapaSmurf]

This or train yu are the best alg trainers. This specifically for ZBLL, OLL or PLL, otherwise train yu.

Have you tried jperm.net

I have not, thanks for the resource! I don't really need it anymore, but thank you!

 

[Nilsibert]

I'm a bit confused. In the bottom right window, the case and the scramble shown are always different from the main scramble above. Why is that?

 

[Pyjam]

It's the previous case.

 

[Nilsibert]

It's the previous case.

Oh, silly me. That is actually quite useful now that I think about it.

You can now switch between top view and 3D view during practising by clicking at the picture.

Switching between flat and 3D view in the selection layout is yet to come.

This has been my main gripe with your trainer so far; the other one you fixed in the earlier post.
Thank you so much for making a great trainer and now for making it even better!

 

[Roman]

Flat view by default.

You can still switch between flat and 3D view in the timer by clicking on the picture.

PS If there are any misoriented pictures or if short/2gen scrambles still appear, please let me know.
If you don't tell me how to make ZBLL trainer better then how else would I know

 

[xyzzy]

short/2gen scrambles still appear,

For the 2GLL pi case with H perm edges, all of the algs are the same 11-move optimal alg.

The short RUL and RUF algs on Birdflu for this case are either Niklas combos or Sune combos, so please don't include those either.

Fair.
Now I have manually replaced this and a lot of scrambles sets so it should be a lot better on the scrambling side.

A few more:
"B' U2 F U' B U F' U B' U B",
"F U F' U B' U F U' B U2 F'",
F U' F2 U2 D' F U F' U D F2 U F'

(Probably the mirror/inverse cases are also affected but I haven't looked yet.)

I like the idea of the random mode, but it seems like when using it, some cases tend to show up significally less often than others. That is of course possible with true randomness. Is there a way to stay in recap mode, with only the order changing? Or better yet, I'd like it to have a sort of "semi random" mode, where cases can appear multiple times, but it would still guarantee that the number of times all the cases that come up is somewhat consistant, if you know what I mean.

Yep, I will do this.
In the beginning each case will have equal probability, and when the case is shown, its probability is decreased 2 or 3 times.

ZBLL trainer now efficiently gives you scrambles to practise all cases evenly during the session.

This feature is rather subtle, but those who practise with ZBLL a lot will feel the imporovement right off.

Spoiler: details

The downside of the recap mode is that after you've done with some cases, you don't expect them to appear anymore, which defeats the purpose. And with "true random" mode, some cases may not appear in the session at all, while others may appear 3,4, even 5 times!

With new probability feature introduced, both problems are mitigated.
When you select N cases to practise, a probability of (1/N) is assigned to each of them. When a certain scramble is given to you, its probability is decreased in half, making this case twice less likely to appear next time. Note that "twice less likely" does not mean "impossible". Right after that, all the probabilities are normalized so that their sum is equal to 1 (or 100%).

Example: you have selected 4 cases. Initial probabilities:
[25%, 25%, 25%, 25%]

Let's say the first one had been given to you, and it's probability is now 12.5%. After normalization, the probs become:
[14.28%, 28.57%, 28.57%, 28.57%].

The probability of first scramble appear again is only 14% — twice less than all others, but they all sum up to 100%.

As you practise, more and more cases get their probabilities cut in half, so at some point the first case will have about the same prob as all others and will likely to appear again. Nontheless, you can't predict when it appears exactly.

This can be interpreted as something between "recap mode" and "just random" mode.

This is solved now.
