I am going to send you a new version of Tornado, but because I am still working on it, I will send you the most recent version when I know when the tournament will start.

Frank.

A good draughts program is characterized by the absence of such blundering moves.

I let kingsrow play it out in autoplay at 2min/move, 16 search threads, and it ended in a black win. Of course that's not definitive. A better way to analyze it is using dropout expansion, to automatically explore all reasonable lines of play and build a db. It would probably take days or even ...

I did a 60 ply search from move 12 and I dit not find an absolute win for black.

With Windows: start cmd (Command Prompt) in the directory where all 22 .pdn files are stored. Give command: copy *.pdn allgames.pdn

Thank you Sidiki for running this tournament!

And congratulations to Joost/Ares!

I have uploaded a test version, and Frank will be the first who will be able to test it.
If it also works on his computer, and most likely some initial bugs, or issues are resolved, I invite others for further testing.
Just drop me a line during the week.....

I have tested the test ...

Hi everybody,

hope you feel good.
I plan to run a tournament the 20th august for fun.

It's a while that engines haven't played against each others.

If someone has an update working well, no problem, it will make the business. Just for fun.

I am free now, for a month and no problem to run ...

For those interested I can issue a version of the Damage GUI, with several engines, so one can do a tournament test out-of-the-box.
Think I needs some 2 weeks for this, and will inform all when this option becomes available.
The only thing i will (most likely) not enable is to broadcast a ...

Bert, an excellent initiative! I'm currently working on implementing the hub protocol in Moby Dam. Just the basics, no pondering or analyzing yet.

Frank, a quit command terminates the engine, not just the game. A game is also ended with a new-game command.


I know the HUB protocol, so I know ...

Bert,

A misunderstanding: I meant additions to your description, no additions to the HUB protocol.

In short: a game is ended exclusively and solely by the HUB GUI, by sending a quit command to the engine.

Frank.

Bert,

Two interrelated additions regarding pos pos=<position>:

The tournament engine should always give HUB commands pos pos=<position> in which moves are possible. Otherwise the engine can't reply with done move=<move>.

Only the tournament engine is able to terminate the game by sending a HUB ...

Very interesting!
Can you please post a preliminary/embryonic version of the minimal set of HUB commands that the Draughts engine must support?

Frank.

Harm already answered that question on Mon Sep 30, 2024 12:38.


That is, it is meaningless to play because you cannot set the most important engine and match parameters.


Only the match parameters are set in mm.exe.
Engine parameters must be set in the engines itself, nowhere else. And this ...

I have one more question. After running the mm.exe application during a match, how many cores will the program play with and what hash will it have.


mm.exe has nothing to do with the settings of MobyDam or Tornado.
As Harm said: start MobyDam with its parameters/settings, start Tornado and ...
