Sungorus 1.4

Post by Pablo Vazquez » Wed Jun 30, 2010 7:45 am

Hi,

Sungorus 1.4 is out. The main changes are:

- Fixed a bug in Swap()
- Added pvs
- Changed some null move conditions
- TransStore(): always replace when there is a hit, regardless of depth
- Mate scores are now displayed correctly

Regards

Thanks Jorge :), but I don't know if there will be much of an elo increase, because I couldn't find the time to work on the evaluation and only made some search tweaks. Dann's test with the pvs version was very positive, though.

Here is a sungorus with pst:

It beat the other in a short contest, but I do not know if it is better or even if my implementation is correct.

When I load the exe in Arena 2.01, I get "Error: Create process"

It's a 64 bit binary. Do you have a 64 bit operating system?
