New android app "BadukAI"

[Vargo]

And an H7 game :

B : CSDL set at 5d , komi 0.5
W : BadukAI 1.3 , KG and the new 40b network kata1-b40c256-s5464776448-d1316114216, Samsung S20+, Android 11, komi 0.5, default settings for badukAI

(some endgame moves omitted : W plays inside his territory, B passes, W plays again inside, B passes, etc. but the final score is the same : B+1.5)

why not test the strongest network?

Two more H7 games, with the network kata1-b40c256-s5390619136-d1297760597

B : CSDL set at 5d , komi 0.5
W : BadukAI 1.3 , KG , Samsung S20+, Android 11, komi 0.5, default settings for badukAI

B+R

W+R (bad endgame by B ?)

[And]

BadukAI s539 1p - CS Zero 8d 0:2
BadukAI s548 1p - CS Zero 8d 1:0

[And]

BadukAI s548 1p - CS Zero 8d 1:1 (W+, W+)
BadukAI s550 1p - CS Zero 8d 1:1 (W+, W+)

[And]

BadukAI s551 1p - CS Zero 8d
in the first game won by CS Zero (W). in the second game, KG resigned on move 172, resignThreshold was -0.99, but after resignThreshold was changed to -0.999 he continued the game and won!

[And]

for some reason KG with the latest networks (kata1) sometimes crashes - "KG is dead/crashed". usually before the start of the game, but today during the game

[And]

installed it on another emulator, connected the network, everything is in order, I wanted to start the game and - crash.
minimized the application to copy the log, deployed, the application rebooted, then everything is fine

The log files don't contain anything unusual. As the 40b networks are quite large, it might be a memory problem. You could try saving some memory by setting

numSearchThreads = 1
nnCacheSizePowerOfTwo = 10

in the configuration, since you are doing only one playout anyway.

[And]

Thank you! there is an opportunity to increase memory in the emulator, what value will be enough?

[akigo]

Unfortunately I can't tell you an absolute number here, as this depends on many factors (how much is needed by operating system and so on). I would recommend increasing the RAM by 50% (if possible), for example if you now have 2GB, try 3GB.

[And]

it was 1.5, I made 2 GB. but there were no failures with the g170-b40c256x2-s509 network before. kata1 networks use more memory? or a new version of the application? Or was I just lucky?

[akigo]

Network size is almost identical, so that can't be the reason.

The amount of RAM needed by BadukAI itself increased when I added the optimization to the 32 bit version, since that involved a lot of extra code. If you last worked with the old 40b network before that, it might be the cause.

Moreover, you are exactly right, there is some luck involved: Even if you only start BadukAI, there are a lot of other processes running (system services and so on), whose RAM usage varies.

[And]

Thank you! I'm glad the BadukAI is okay! I found lz 40 block works fine on my tablet! I have 20 blocks freezing! incredible!

Thanks for the great app! Everything works good on my phone (snapdragon 845, gpu adreno 630) but not when I try to load a new katago network. I took the network from my PC, loaded it on my phone but the app just doesn't see it. I've tried it with both .txt and .gz format - still doesn't work. The app only shows me an empty folder while there's sure some katago nets.
I use the last 1.3.0 version and already loaded katago 10 and 20 block nets works fine.
What could be the problem here? Or perhaps I am doing something wrong?
