Your solutions are always very efficient. How many different solutions do you typically go through before arriving at your final solutions?

If you can keep my secret, I will tell you that, for more than a year, I am developing a software to find optimized solutions for different methods: CFOP, Roux, Petrus and ZZ. I am using the solutions in these forums to tune up the application. The solutions that you and the other users posted are very helpful and gave me lots of ideas for improvement. The good acceptance of the solutions I posted is for me a confirmation of his usefulness. I plan to release it before the end of this year as free software.

Here's a screenshot:

Id like to discuss this more in DMs if you're willing.

How many algsets does it know and use?

How does it perform Petrus EO? Does it know EOpair/APB? Would you consider adding EOpair/APB?

BTW, the Mehta user base is pretty large. You might consider adding it as well? All it would require is for you to add the logic for building 3QB and the algs for EOLE and TDR in order to support the "main" variant: Mehta FB, 3QB, EOLE, TDR, ZBLL.

Mehta-OS would be a whole different can of worms but would help a lot in determining the optimal option for a given scramble. (There is very little consensus around how to best determine this at this point.)

I plan to implement yruRU, Metha and Nautilus methods in the future, but now I want to release it with the methods I know.

The last 2 -- to some extent -- would be pretty easy given that it can already solve using Petrus and Roux. YruRU would be interesting just to see what the CN (or non-CN) optimal CP lines would be.

the Mehta user base is pretty large.

Yeah it is large if you consider 3 people as a big number(idk how many people switched since I quit discord lol)

Wow this actually seems pretty cool!! When do you plan to release it?

Yeah I'm interested to know how the optimal YruRU solve(especially the optimal CPLine) looks like.

Well, it wasn't really a secret if he decided to release it at the end of this year.
