Unified BLD Algorithms Database

[mark49152]

For a long time I've wished there were an equivalent of speedcubedb or algdb for BLD algorithms, to save having to search across so many individual alg sheets. So, finally, I got round to making one.

https://bldbase.net

I hope you find it useful. It's a work in progress so consider it "beta" and please do let me know of any issues. Ideas for improvements are of course very welcome too!

Update: It now has corner & edge comms, wings, midges and centers for bigBLD, and 3BLD parity algs.

Just took a quick look and it looks awesome! I’m glad to see a nice bld resource site that gathers some of the best resources into in place!

Maybe ask @Gil.zussman to add it to his site

Nice!
Question: If I update an alg in my sheet, will this database reflect that update?
Recommendation: Add in some user settings so that people can specify their letter scheme and see that instead of UFR-notation and Speffz.

Hi Kevin, thanks! And thanks also for sharing your sheet & algs.

Yes, if you update your sheet the new alg will be added and the old alg will also be retained. I have a script that scrapes all the Google sheets I know of, checks anything that looks like an alg, works out what they do, and adds all the correct & useful algs into the database. It's manual at the moment, but I might set it up to run weekly or even daily.

It also spits out a list of typos/errors for each sheet and I can provide those back to the sheet owners - if you or anyone else would like that, just let me know. It will detect algs that don't appear to do anything useful, e.g. due to typos, and some of those I just fix in the DB. However, the script ignores labels in the sheet so it can't tell you if a correct alg is attached to the wrong case.

For yours, there are a lot rejected but that is because of the ! symbol, e.g. [R: [U2!, R D R’]]. What does that notation mean? It looks like I could just safely ignore the symbol, is that correct?

Customizable letter scheme is definitely on my to-do list, once I have all the alg types in there.

Ability to quickly find the alg based on the letter pair from custom scheme would be fantastic.

Yes, you can ignore the "!"s. I just use them to indicate that the inverse should be in the same direction. So (U2!)' is U2 not U2', and the above becomes R U2 R D R' U2 R D' R2' as opposed to R U2 R D R' U2' R D' R2'.

Glad to hear about the script, and that you plan on allowing customized letters.

LOL, nice to think people might appreciate the site, but I've got no plan to accept donations!

OK, fixed. My code pays no attention to the direction of half turns anyway.

Just updated the site with parity algs, plus some other general improvements. Custom letter scheme is next on the list.

Thanks for the site Mark! This is so much easier than tabbing through different spreadsheets and locating the right cell.

Btw, there are two Ts in Elliott.

Apologies, fixed now. And thanks for sharing your alg sheet!

 

[eyeoh]

Oh just to be clear - I'm not Elliott, but I have made the same mistake before when spelling his name when talking about his sheet!

Ah OK - thanks anyway for the correction, and the clarification!

Really good tool.

One feedback that I have is that DF edge buffer should be removed. DF is much inferior as compared to any U layer buffer. Even beginners should not try out DF in any situation or circumstance. Beginners UF buffer methods are BOP and Eka.

Thanks! You've already given that feedback on Facebook and unsurprisingly will get the same answer here . It's a database so includes all the main buffers and all the published algs for them, regardless of personal preference. People can choose whichever they prefer.

I appreciate your concern but please let me decide on my own what buffer I will use even if you think I'm hurting myself.

Please keep DF buffer.

Yes and as someone who doesn't think 5-Style is worth it I think you should abandon it since it's a poor use of time compared to other real-world studies.

I thing I have against you also is that you don't main the Qiyi MS. The Qiyi MS is far superior to any Moyu cube and I don't think anybody should buy one, much less main a cube other than the MS.

I think that we as a community should sue all other companies so that you can only use my cube.

Because I only started learning 3-style corners a bit over a month ago (after getting familiar with Orozco as a test for myself earlier this year), my edges are still done with M2 and will be for some while longer.

So, as far as edges go, I've actually referenced some DF algs in various sheets for M2 (for basic 2-flips, as well as DF-FU/BD, etc). It was also nice to look up algs being taught in various tutorials and see where they "originally" came from; including deciding between which fingertricks to favour.

Everyone who's starting 3-style these days would have stumbled upon stacks of resources favouring UF, so I doubt there's any risk of accidental confusion here. Where the value in a database lies is seeing stuff in context, including historical data for purposes of comparison, etc.

As for BOP for beginners, I have my views against it but won't derail this thread with them as I understand there's an existing BOP thread.

Ooops, sorry if I offended you in some way. I am open to all ideas (related to cubing hardware or software).

Its just that I do not want people wasting their time with DF buffer.

@mark49152, which of Jack Cai's sheets is being polled?

For UFR-FDR-DBR / Speffz KW, Jack is only listed next to [D R2 D2: [R U R', D]], but all the sheets I've found have [U R D': [U', R' D R]].

The ones I've checked: Jack's 3-Style Algs 2021, Jack Cai's 3-Style Commutators (updated 2020), Jack's 3-Style Algs v2, Jack Cai's Starter 3-Style Algs.

I'm guessing there's (at least) one more sheet of his I'm missing?

Edit: Oh, it must be this one (the 2nd one listed on Roman's tables) - which looks like his first sheet: Jack's Comms
