Sample Java Bot

Jeff Bacher (developer of bot Clueless) has contributed
a sample Arimaa bot written in Java. Developers can
simply enhance the evaluation function to build their
own bot. I've added it to the download page:
http://arimaa.com/arimaa/download/
Thanks Jeff.

Hey, that's pretty cool; I'm developing in Java as well.
I was thinking of releasing my class library that models all the basis elements of Arimaa, but looking at jeff's it may not be necessary; they cover most of the same ground (although in a rather different way; Jeff's code is very "C-like", mine is more like what you'd see in a design patterns textbook. Which means mine is undoubtedly much slower...). It might just add confusion to have two incompatible java classlibs floating around.
But thanks much for releasing this; I've pretty much only been working on my eval function, figuring I'd code a tree searcher in Java down the road some day (or port to C). This will help quite a bit.

I have downloaded his program and found in the main he wrote a comment
// Used for testing purposes
// String file_name = "c:/arimaa/bot/running/gamestate804";
// execute(file_name);
Where can I find such a file so that I can check the program first without any effort?
Can anybody provide me with such a file so that I can start a test of the bot?
Regards.

The test you mentioned was for testing the gameroom interface. It is not necessary to know about that to use the engine.
To run the engine intself, I suggest starting in ArimaaEngine. It contains a program entry point that allows the engine to run on its own.

Hi !
Thanks for the reply. I have tried that. But I am getting java.lang.OutOfMemoryError: Java heap space error. I am using eclipse IDE.
I have tried to run the app with
-Xmx500000000 but it is still showing the same error.
Would you please recommend a valid heapsize for this?
or Am I missing anything?

The exception I am always getting
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
at arimaa3.ArimaaMove.<init>(ArimaaMove.java:
at arimaa3.HashTable.<init>(HashTable.java:30)
at arimaa3.ArimaaEngine.<init>(ArimaaEngine.java:433)
at arimaa3.ArimaaEngine.main(ArimaaEngine.java:1314)
May I get any suggestions?
Regards.

Jeff can probably give you more details later, but I think you can reduce the heap size until you find something that works.
Try something like:
java -Xmx30000000 -classpath test.jar arimaa_bb.ArimaaMain
to give 30 MB for the heap.

No, that does not work, too.
By the way, now I am trying to understand the sample perl bot.
Regards.

500Mb should be plenty for the heap. Maybe eclipse is doing something. Have you tried running it from the command line?
