How can I configure Rodent IV in Android chess GUIs?

[tapio]

Hi guys,

I'm using DroidFish and the awesome chess engines collection from:
https://sourceforge.net/projects/chess- ... -oex/files

Rodent 4 has a) personalities decoupled from b) ELO.
b) is what I don't know how to set.

a) Setting personalities txt files via the file open picker in the engine settings is impossible, because nobody on earth knows where those files reside in the filesystem. I just entered grumpy.txt and hope it uses it. Maybe that part is solved.

b) Rodent doc says "[...] the latter – by setting UCI_Elo
parameter. " How? Where would I find such a setting?

b) is a crucial point, because playing Rodent 3000+ ELO is not why I chose it.

Thank you!

I wanted to add a screenshot, isn't that implemented to the forum, or just not for new users?

Ugh thx, I overlooked it, because I expected it inside or close to the "Manage chess engines" slider.

It seems that this is also possible: https://github.com/peterosterlund2/droi ... ci-engines. See the part with DroidFish/uci/logs as working directory.

Ah, so I can put the personality files there... a bit messy, but I hope it works and they are used.
I wonder why if there is a working dir, why the file picker in engine options doesn't start there.

Rodent will not work that way unfortunately. Thanks to Archimedes findings, this is the solution for R4:

Rodent 4: Binary goes into droidfish/uci/, books/ and personalities/ to storage/emulated/0/Rodent4/ - engine option in DroidFish will then allow to pick PersonalityA and PersonalityB from a dropdown.

Rodent 3 DroidFish: Whereever you put books/ and personalities/, R3 does not seem to find them. Impossible to solve for mere mortals

Acid Ape vs Rodent 4: We have an oex apk binary, but I find no way make it use pers/books. Probably a scope issue.

It's all a real PITA. My guess is, people use Rodent on Android and are unaware that it's not necessarily using personality and for sure not personality books.

In any case, the variant with the installation file (APK file) also works under DroidFish. Provided that you copy the two directories books and personalities into the /storage/emulated/0/Rodent4 (/sdcard/Rodent4) directory. The two directories are available in the assets directory (simply rename *.apk to *.zip). In Rodent III you will probably have to make some changes to the source code to make it work like Rodent 4.

In any case, it works so far with Rodent 4. Better a bird in the hand than a pigeon on the roof.

Some time ago, the author also offered a NNUE version for testing.

Seems to work under DroidFish. At least the books are recognized. You would have to test whether the personality files work.

I don't find an Android binary in that 7z file?
