Beowulf 2.2 b4 JA (Fischer) update

[Jim Ablett]

Engine : Beowulf 2.2 b4 (Fischer personality)
Authors: Colin Frayn and Dann Corbit

Changes:
v2.2b4

1. Bug fix #2 for the "Could Not Find First Ply Hash Entry!"
intermittent problem.

Made changes to hash key and forced a 'hash elements and staleness'
check after every search. (No performance hit in my tests)

2. Made some internal eval changes. Hopefully a little stronger.

3. Updated to WB2 protocol.

4. Special Intel 'auto parallelized' optimized build (libguide40.dll' included).
This means all program code loops are executed in parallel wherever
possible. The end result being faster and more efficient operation.
(That's the idea anyway!)

Any feedback on strength and stability welcome.

Available from my homepage.

[Jim Ablett]

Made a very small revision (noticed Beowulf was resigning too early).

Same version number.

Please re-download from my homepage
(if you already have before this post)

Another update:

Changes:

v2.3b5


1. Ponder bug fixed (introduced in 2.2b4).

2. Updated to 2.3 source code and incorporated all
previous bugfixes/changes.

Available from my homepage.

Jim.

[Dann Corbit]

Are there fixes to the 2.3 base that I do not have?

[Jim Ablett]

Hi Dann,

I've added the modified src to the download file now.

It's normal 2.3b4 src plus my small changes.
Load it into MSVC++ and type 'JA' in the search to find them.

regards,
Jim.

Here's a good win for Beowulf as black against Yace Paderborn.
Yace's queen is totally neutralized allowing Beowulf to control the game.
