BTW, I already verified the same Lazarus project compiles and runs on Windows. Perhaps it will also compile and run on Mac, but as I don't own a Mac I cannot check this myself (and I would have to port GWD to Mac also).

so did it work and can you swap Hub engine or play a engine match ...

you can instruct the AI to put up a GitHub Actions workflow and test it ...

That is really awesome. I have been having great experiences with AI tools too. E.g. I have an algorithm to index/de-index kings only endgames with symmetry equivalent positions removed. I just prompted regular ChatGPT and it wrote Python and C++ code! I was planning to try a Qt C++ GUI next, with ...

Good news everyone,

I have just released an update of Moby Dam. This version supports the HUB protocol, in addition to the existing DXP protocol.
Read notes.txt for an example of how to use Moby Dam in hub mode with Fabien Letouzey's hub_21 GUI.

The program can be downloaded at https://hjetten ...

On https://toernooibase.kndb.nl/opvraag/applet.php?kl=23&Id=48077&r=12&jr=26&wed=1734979&taal= Martin Dolfing explains that he missed a very good opportunity on the 8-th move: 8. ... 21-27 9. 32x21 17x37 10. 41x32 20-24 11. 29x20 15x24. This seems like a nice challenge for computer draughts ...

Het probleem van de naamgeving voor openingen is inderdaad soortgelijk. Door het ontbreken van precieze definities is het in veel gevallen niet duidelijk waar de grenzen liggen. Nu zijn er tegenwoordig natuurlijk neurale netwerken die je zou kunnen trainen in het herkennen van namen. Dat is ...

Apparently @murraycash computed perft(29) in November 2020: https://oeis.org/A133046
Anyone up for the task of confirming that number?

ja zeer leesbaar, geen onnoemelijk diep vertakte variantencomplexen zoals in het Andreiko-boek.

Gisteren viel het dan eindelijk op de mat: het lang verwachte eerste deel van Sijbrands damtechnische automonografie. Mijn hemel: wat een megalomaan project. Vergelijkbaar met de romancycli De Tandeloze Tijd en Homo Duplex van A.F.Th. van der Heijden. Een recensie kan pas over een halfjaar ...

Aha, I have to admit that I didn't look at the code snippet and blindly assumed you were using TMP. It's truly amazing that the compiler is capable of checking a complex function like perft() with a static assert, I never thought this would be possible. Of course you could do this with TMP as well ...

Because template meta-programming is Turing complete you can do these things. It's is a nice programming exercise, often these techniques are not very usable in practice though.


Ah but this is not template-metaprogramming. Just a regular perft() function but called inside a static_assert ...

What's faster than running perft() in a few seconds? Running perft() in zero seconds of course! And I don't mean computing perft() numbers at program startup time, store them into a table and reading them out again. No, I mean computing perft() completely at compiletime.

Another exotic board layout! Here's the 10x10 board embedded into a 29x10 grid:


5 6 7 8 9
19 20 21 22 23
34 35 36 37 38
48 49 50 51 52
63 64 65 66 67
77 78 79 80 81
92 93 94 95 96
106 107 108 109 110
121 122 123 124 125
135 136 137 138 139


Why on earth would this be useful? Well ...

13 Elo compared to what? What is the benchmark here?
