Tucano chess engine 1.00

[sedicla]

Hello, I made available my chess engine with source code. For now I just have the windows 32 bit executable. I implemented xboard protocol.

I've been working for some years in my spare time, and I choose the name tucano (or toucan in english) because I want something related to my country Brazil.

Thanks to everyone that contribute to chess programming, mainly CPW, talkchess, and all available source codes.

I implemented a basic bitboard with no magic, rotated style. I left some of my testing routines that my help others, such as epd test, eval test and 3 types of perft.

Hope you enjoy. This is a very addictive hobby. I'm planning to keep working on it.

Thanks
Alcides.

Hello Alcides:

Congratulations because I am unable of write a chess engine: it is an impossible task for me!

Someone in ImmortalChess forum noticed a lapsus in readme file that should be corrected:

The only real limitation is that whenever you distribute DoubleCheck in some way, you must always include the full source code, or a pointer to where the source code can be found. If you make any changes to the source code, these changes must also be made available under the GPL.

Good luck with the development of Tucano.

Regards from Spain.

Thanks, it is fixed now.

Hi Alcides,
Welcome to this hobby! I compiled your engine for ARM to test importing it in Chess for Android (and with your permission I eventually would like to post the engine on UCI and XBoard engines for Android).
However, it seems a bit of work is required (<= is output of engine, => is input from GUI to engine).

Code: Select all

<= tucano chess engine by Alcides Schulz - 1.03

=> xboard
=> new
=> hard
=> easy
=> post
=> st 1
=> go

<= move e2e4
<= 1-0 {White mates}

FWIW, I have it now more or less working with some quick hacks in your sources....

Awfully long game, there!

Sarcasm aside, congratulations for writing your own chess program. My own program Durandal (currently private) took a hell of a long time to create.

Yes you can post there, thanks.
I wonder what went wrong, if you send me the changes you made I can take a look and include in my original.

Thanks again.

Most notoriously, don't use plain "char" if you need it to be either signed or unsigned. Simply make the full type explicit.
In general, I would strongly recommend you compile and run/test your code on Linux to deal with a few other portability issues.
I am happy to test a new version once you have one.

Ok, I'll try that. I'll keep you posted.
Thanks.
