caissa's Issues

Reflect a bug in Caissa1.14.1

3r3k/7p/2Q5/8/2B2PK1/6P1/4P3/5q2 b - - 98 99
Please forgive me for my poor English. Caissa1.14.1 is very powerful! But there is a bug, the above situation went through Rd8-d4 in the engine league, resulting in one step being killed by the king. I hope to correct it.

Mac compatibility

A few things I noticed when building for Mac:

ftello64 and fseeko64 -> ftello and fseeko in
https://github.com/Witek902/Caissa/blob/master/src/utils/Stream.cpp

sprintf is depracated, snprintf seemed to build fine. Needed to be changed in:
https://github.com/Witek902/Caissa/blob/master/src/utils/ThreadPool.cpp
and
https://github.com/Witek902/Caissa/blob/master/src/backend/syzygy/tbprobe.cpp

about the Contempt options

hi,

i just managed to compile your v1.12 on Xubuntu 22.04, AVX2 version .. i see two "contempt" options 'Static' and 'Dynamic' .. what are those ?

as i understand 'contempt' is something like 'optimism' .. i can imagine how playing style & bestmove can be different when setting such values .. maybe you even have test positions to show the effect of these options ?

how to get PNN file ?

hi, i managed to compile your newest Caissa on Linux .. the UCI info says v1.6.11 but also : Failed to load default neural network eval-7.pnn .. indeed this file is missing, where to get it ?

Android compitability

Any chance that the source code will become compatible with Android again (arm64-v8a and armeabi-v7a)?

connection stalls in CuteChess

i let Caissa v1.3 play several games in CuteChess .. all went well but it lost the last game on time : "connection stalls" .. see screenshot. At that moment Caissa had a lost position anyway, maybe that was the cause, but it shouldn't happen. The CuteChess log did not show anything. I don't know what can be done to fix this, i just want to mention this incident.

Caissa 1.11 disconnections/Crashes/Timeouts

OS: Archlinux

Caissa works, tested in Nibbler GUI and everything was fine yet it seems something is wrong as I try to make it play games against other engines in Cutechess gui nor BanksiaGUI. I am curious about if it is also the same for Windows.

Please add ARMv9.2, SVE2, Dot Product and Neon support

It's sad that it's not possible to compile the newest version on Android and Linux devices.

unable to compile v1.7 on Linux

again i'm unable to compile your (v1.7) source files on Linux .. i tried to get the source files by git clone and also the supplied ZIP, both fail :

[ i'm on Xubuntu 22.04 ]

Compiles

Hi,

may you release a non-AVX2/BMI version too, please? I can't run it, I'm limited to AVS and SSE.

Thanx,
Alex

more endgame knowledge

hi, your v1.9 release page states "Add more endgame knowledge, should evaluate some fortress positions better" .. well, a known issue here is mate with 2 kNights, which will never happen, but many engines do not fear to exchange pieces and pawns to reach such position, while they think it is winning due to the material balance .. however, without a pawn, White team KkPP will never win, eg. see https://en.wikipedia.org/wiki/Two_knights_endgame .. Btw. also read about the exception : the opponent might have (only) one pawn, then a mate is possible ..

is Caissa aware of this matter ?

Android NDK

When I compile with Android NDK (which uses the Clang compiler) by using the flag "-DUSE_ARM_NEON", I get the following error message:

backend/PackedNeuralNetwork.cpp:544:33: fatal error: no matching function for call to 'vaddq_s32'
val += vaddvq_s32(vaddq_s32(vaddq_s32(sumA, sumB, vaddq_s32(sumC, sumD));

I assume the line must look like this:

val += vaddvq_s32(vaddq_s32(vaddq_s32(sumA, sumB), vaddq_s32(sumC, sumD)));

Finally, an additional "#include <cmath>" is required in Evaluate.hpp.

With these changes, Caissa compiles smoothly with Android NDK.

Polyglot book compatibility

hello, please add book support,Thanks.

AdjustTokenPrivileges failed, error code: 1300

When running caissa-1.13.1-x64-avx2-bmi2.exe under Win11 I get following output:

AdjustTokenPrivileges failed, error code: 1300
Caissa 1.13.1 AVX2 by Michal Witanowski
info string Using embedded neural network

Engine seems to be working fine...

EDIT: do not have this on other machine with Win10
also found this, but not sure it this is related: https://devblogs.microsoft.com/oldnewthing/20211126-00/?p=105973

compile on Linux ?

is the source code also for Linux ? I guess not .. after doing cmake -DCMAKE_BUILD_TYPE=Debug i get a makefile .. then i do make but i get these errors :
