New release Pedone 1.6

Post by Fabio Gobbato » Sat Jun 10, 2017 10:03 am

I have released a new version of my engine.

The changes:
Android executable
Max Threads set to 128
Simplify king safety and increased sensivity
Improved threatened pieces evaluation
Tuning
Added some more endgame knowledge
Tuned reductions
Improved history heuristic
Tuned iid reduction formula
Some speed optimizations

The difference between version 1.5 is between 20-30 elo

You can download it from its web site: https://sites.google.com/site/pedonechess/

Very exciting to see an Android build. Thanks for this.

But some issues:
* Lenovo Vibe S1 with octacore MTK6752 Lollipop 5.0 64 bit: No issues. :D
* Galaxy Note II with quadcore Exynos 4412 Kitkat 4.4.2 32-bit: Exits after choosing UCI in Chess for Android. Droidfish gives also error. :(
* Galaxy Note II with quadcore Exynos 4412 JellyBean 4.2.1 32-bit: Same error as Kitkat.:(

By the way, there's also another user reporting that it works well with quad core cpu & 32-bit Kitkat which surprised me because the same config doesn't work for me.

This is the first time i had a 32-bit build running on a 64-bit O/S but not on 32-bit.

Can you please check what's going wrong because Pedone is closed source and you're the only one who can help. Regards.

On My computer, Pedone hangs both from Sabrina tourney-mode than running from the command line. This is the log:

Code: Select all

W	--->	quit
B	--->	quit
"W" commands are those sent to Pedone. My PC is:

Intel i7-4790K at 4 GHz 8 Gb RAM - Windows 64 bit

It hangs the same as "Pedonw_win.exe" and "Pedone_win_nopopcnt.exe".

You have launched the engine without the position command.

Ok, now it go ahead but still it hangs. This could be a problem in my GUI, not in Pedone:

If I feed the commands from the commandline I get this (Pedone 1.6 nopopcount):

In the second log Pedone was playing with Black. Maybe now the problem gets from something related to timing in my GUI (but the GUI itself doen's hangs).
