Teki chess engine

[mkchan]

I have released Teki 1 after the random mover last time.
It is available here:

https://github.com/Mk-Chan/Teki/releases/latest

It is a basic engine right now with focus on simplicity (hopefully). It should have approximately 2200 strength.
I want to add FRC support ASAP and cover as much of the UCI protocol as I can following that with Threads, EGTB, MultiPV, Pondering, etc. before moving forward with anything else.

Hopefully the windows executables are working fine

Thanks for this one Manik.
The 64-bit version works here on my no popcount hardware.

Hi Manik,

thats great. Thanks.
I like the idea to have a SMALL engine with its basics alot...Mainly cause i wanted to learn how to do chess engines again..I did that 1000 years ago, but im out of business

I know the uci is not ready/finished...but pressing a CR let the engine calc forever (until "stop") when a best move is displayed. Prob. very easy to "fix".
On my linux it works, but i had to change the build.sh line 68 cause i dont have a cmake. Perhaps y can test this (too)?

Looking forward to see more of Teki. Thanks again.

Hi Jurgen,

I made the cmake thing just for flexibility. You can build with the makefile in src/ if you just do

Code: Select all

 make BUILD=release 

It will produce a simple 64-bit non-static binary. It uses clang by default but you can change it with

Code: Select all

 make CXX=g++ BUILD=release 

I just personally prefer clang. Not looking to min-max the speed in Teki

Just to inform anyone interested, I have relicensed Teki from GPL to MIT.

Hi Manik,

It builds fine on the 32bit Linux Raspberry Pi by using the provided Makefile.


Thanks,

Al.

Thanks Al. I have compiled and uploaded a binary from my Raspberry pi too. It should work on Android phones as well (both being ARM) but I've not been able to get it to run on my phone yet.

I think I managed to get the android version working fine. It'd be great if someone could try it out and tell me about it.
I tested it on Droidchess and Chess for Android.
It's available here: https://github.com/Mk-Chan/Teki/releases/tag/v1.0

Can't get it to work. Both on an intel pc as well as a raspberry pi:

Sorry for the confusion, if you compile by yourself using build.sh (which is the cmake build) it will compile static binaries so you need the static linking libraries like glibc-static or whatever on many linux distributions.
You can remove the line containing "-static" from build.sh or just use the makefile:

Code: Select all

make CXX=g++ BUILD=release
