IvanHoe 999953 beta

[kingliveson]

999953 Changes seem good -- fixed a couple minor bugs. Significant change is introduction of magic bit-boards; unfortunately, it's a 2% speed hit. Will upload when ready.

[Vael Jean-Paul]

Great..again a new compile..but what does these magic bit-boards do?

Great..again a new compile..but what does these magic bit-boards do?

I like your optimism. Magic bit board: http://chessprogramming.wikispaces.com/Magic+Bitboards and http://en.wikipedia.org/wiki/Bitboard#Chess_bitboards.

But Understand the nature of beta software development and its frequent releases. If you think of Rybka, whenever significant changes are made, resources galore (including CCRL, a department of Rybka enterprise) are available for testing. Not so with IvanHoe which is more community based. We (you and I) are the testers -- we let the developers know when there are issues or features that need a second look. I would say they are quite generous to continue working on a regular basis to improve this amazing chess program. It has come a long way from its Ippolit beginnings.

IvanHoe 999953 beta builds for Linux/Windows are available: http://chess.cygnitec.com/engine

999953 is slower than 999954 that was re-uploaded. Currently running a 40/40 repeating tournament on very weak hardware, single core CPU with 999954 vs Rybka 4. Ponder off, 256 MB Hash, no EGTB, Rybka using recommended TC3.100.150, and IvanHoe is using default settings except Pawn Hash (set to 64 MB). Score is tied after 10 games. 40 more rounds to go.

If Mr. Martin T is interested, for his next long match tournament, it would be nice to see Rybka 4 vs IvanHoe 9.54b. Only thing IvanHoe needs is Pawn Hash set to 1/8th or 1/4th of Hash used -- everything else can remain default. 999954 beta is quite stable as is 999953.

Only thing IvanHoe needs is Pawn Hash set to 1/8th or 1/4th of Hash used -- everything else can remain default. 999954 beta is quite stable as is 999953.

Hi! What do you mean by this?
If I'm using 1024 mb hash so I need pawn hash setyp as 256 or 128?

Hello Mr. Doe, yes Pawn Hash needs to be adjusted relative to Hash. The Pawn Hash gets quite a hit during search (eval) so setting it too low causes nps to decrease. You can't go wrong with 1/8th. Just like Hash, must be power of 2.

Ivanhoe 9.53b x32 default doesn't run on older pcs because popcnt is turned on---when I run the exe in a dos window, it reports popcnt enable.

Actually, I no longer have IvanHoe 9.53b w32 source code. I was careless, but am definitely keeping the source for the next build though. Inside joke.


Thanks for noting, fixed file has been re-uploaded.

Can't you decompile it and make it even stronger?

Works fine. Thanks.
