No, those are mobydam.exe arguments. Not applicable for mm.exe. You need to keep things separate: make a shortcut for each of the engines, and a shortcut for mm.exe.

You will need to make a separate shortcut for mm.exe. For example: "D:\Moby Dam International\mm.exe" -m 80 -t 10 -1 localhost:27531 -2 localhost:27532 "D:\Moby Dam International\2-move ballots matchfile.fen" Assuming mm.exe and the fen file are both copied to the D:\Moby Dam International folder. A...

Krzysztof, I think you can do this with my tool mm.exe, which sets up a match between two DXP engines. mm.exe is included in the mobydam zip archive, in the test folder. Usage: mm.exe [-m n] [-t n] [-1 host:port] [-2 host:port] matchfile -m n = moves per game (default: 80) -t n = time per game (minu...

Hello Krzysztof,

It was a good test, and nice to watch live. But what happened at the end of game 6?

Hi Bert, Here are some recent results of Moby Dam 2023 against Kingsrow and Scan. All programs use 6-piece egdb, 512MB tt, 1 thread and no pondering. DXP match settings 1 minute for 80 moves, on my i3 12100. kr 1.63 vs moby results for first engine: +144 -3 =1498 ?5 54.3% sc 3.1 vs moby results for ...

Hello everyone, Good news! A new version of Moby Dam is out. There are two main changes: multi-threaded search, and pattern based evaluation. The playing strength has improved quite a bit, though not to the level of Scan and Kingsrow. The program can be downloaded at https://hjetten.home.xs4all.nl/m...

Hi Krzysztof,

You can set the number of moves to 0 instead of 75; 0 means "unlimited" moves.
Of course Moby Dam will then play a bit faster so by move 75 it will have used maybe 12 or 13 minutes, to account for the possibility that the game will be much longer.

Hello all, just a heads-up that a new release of Moby Dam is available. This is the version that I used at the tournament in Amersfoort on May 19. The changes are minor, I don't expect a noticeable increase in playing strength. Enjoy! Edit - Here is the link: https://hjetten.home.xs4all.nl/mobydam/m...

A new version of Moby Dam is now available for your perusal. This is the version that I used past weekend in the Computer Olympiad 2016. Go to http://hjetten.home.xs4all.nl/mobydam/mobydam.html See the bottom of the page, "second release." The zip file contains the source as well as a 64-bit Windows...

Hmm, I imagine WebSocket to be suitable for a draughts GUI in a web browser, talking to an engine on a server. On the server side you would need a web server that sends the GUI Javascript/HTML5 code to the browser and then keeps a WebSocket channel open to communicate. The web server could connect t...

Catherine, I am not aware of any problems with multi-part captures, either with Scan or Dam 2.2.
If you saved the game or made a screenshot please post them to the board or mail it to me, so I can investigate.

Jaap Bus analyzed the Scan - Moby Dam game at his blog, see http://endgamesandmore.blogspot.de/2015/08/a-very-interesting-game-of-computer.html . His conclusion is that 26... 11-17 was not fatal, Moby Dam could still have reached a draw. At move 33... instead of 12-18 it should have played 15-20 and...

Or, instead of adding that line, you can add ws2_32.lib to the project configuration properties,
All Configurations, Linker - Input - Additional dependencies.
(At least, that's what I did in VS 2013).

The link-time optimization option is present (-flto), so it might be good to add -O2 to the LDFLAGS as well.

From a Google search I get the impression that it's a bug in gcc 4.8.
There is mention of a workaround.
Try to make the Makefile section look like this:
