Twisted Logic 20070706 released!!!

Post by Edsel Apostol »

Hi Everyone,

I had stopped development of my engine for around a month now because I'm too busy with work and the PC that I'm using before has finally succumbed to old age. That means that I don't have a PC at home anymore. That's why I couldn't develop my engine as I wanted to.

By the way, I still frequent the forums almost everyday and I just can't resist to release a new version. The only changes are making the prunings and reductions less aggressive as it leads my program to play weak moves, and a major bugfix in the search routine, thanks to the author of Petir, Peter Alloysius for pointing that out in my source code.

We had a mutual source code review. I apologize to him if I had not reviewed his code much becuase of the reason in the first paragraph above. I will make it up for this someday.

Anyways, I'm compiling this version on an internet cafe, and therefore I have not tested it much. Testers out there are very helpful in my case. Thanks people!

This version I'm sure will be stronger than the previous versions.

Feedback is welcome. You can find my e-mail address in my homepage or in the readme file.

Hi Edsel,

did you manage to find out why the previous version kept losing on time?

Regards, Graham.

Hi Graham,

I don't know the answer to that. I only tested the engine in a few 1min+1sec time control games and it didn't crash or lose in time.

Does my previous engine version before crashes or losses on time? If it did crash, is it somewhere in the middle of search or it is before it outputs any principal variation? Or if it losses on time, what time control was being used and from what move number it losses on time? Does it use its time evenly or it just thinks for a certain position indefinitely and therefore losing on time?
