Re: CSVN tournament, in Amersfoort, the Netherlands

Amersfoort is a good location for me but unfortunately I cannot participate that weekend.
Good luck all and see you next time! :)

Re: Java problem

Hi, Java 11 is installed, however it is impossible to run your engine. Pity. There is not a simpler way to turn it ? :( Running my engine with OpenJDK is not that difficult: download the OpenJDK, unzip the zip file, go to the bin folder and execute the following command: java -jar [location of ches...

Re: Java problem

Best option for engine testers is to use OpenJDK I think. It is free and runs Java 11 binaries.
One drawback is that there is no executable so you have to add the java.exe manually to your path.

Re: chess22k 1.12 released

How does one make it use 4 cores or 8 cores? Would providing bat files for each make it easier for the user (as with the latest Pirarucu)? Using multiple cores can easily be set by using the UCI threads command. Or do you really need that it can be set using a .bat file? But as is mentioned in the ...

Re: new Engine, Axolotl

Hi there, thanks for the link! Yet another thing I should implement. However when talking about phase, I was thinking of a particular part I have seen in many engines: If I may quote from your engine (I hope this is ok) while (phase <= PHASE_QUIET) {} this is written within the negamax search, and ...

Re: new Engine, Axolotl

Thank you very much for these two tips, I will get right on this. I have also starred your engine on github - it is extremely impressive! I hope to give it a good game someday. If I may ask you one question with regard to your chess22k engine: I notice you use PHASE objects (/int) in many parts of ...

Re: Java problem

Guenther, the main reason I have JRE 8 installed is that we have some old 32-bit Java entries on our lists that have accumulated hundreds and thousands of games, it would be counter-productive to start testing their 64-bit versions as in my experience the gain is negligible -- unlike with C/C++ eng...

Re: Java problem

Ok I checked a few very old ones and they really throw an exception. e.g. Eden_005 and Ronja_060 (despite being much more recent) Currently I have only installed JDK 11.01. Java versions are indeed backwards compatible. It is true that they removed some libraries from Java 11 to make it leaner. If ...
