thanks to Tord, Marco and Joona for the well-commented top-notch source code/engine...

thanks also to Jim for the advice on compiling...

There is only one line change:

Code: Select all


// Null move dynamic reduction based on depth
-        int R = 3 + (depth >= 5 * OnePly ? depth / 8 : 0);
+        int R = 3 + (depth >= 9 ? 1 : 0) + (depth >= 15 ? 1 : 0) + (depth >= 21 ? 1 : 0) + (depth >= 27 ? 1 : 0) + (depth >= 33 ? 1 : 0) + (depth >= 39 ? 1 : 0);

Why do you think this single line change re null move reduction merits changing the name of the program? A code fork merits a name change if and when there's a significant modification of the code. This ain't anywhere close. Nevertheless, it's interesting.
Answer: To differentiate my modification from the versions being developed by the Stockfish team (of which i am not part of). Nevertheless, i recognized Stockfish as the base code (just like Crab). Regarding the "amount of code change" to affect naming of the program, i don't believe in that. Why? There are people who are minimalist...:-) i.e. Pareto principle follower.

Hi Ed. Thanks for these settings, i'm currently testing them. I also had an idea to combine your settings with the Stockfish 1.8 Tactical settings by LucenaTheLucid -
http://www.open-chess.org/viewtopic.php?f=7&t=366

Not enough games yet to be conclusive, but it looks very promising. Here are the settings for Tinapa 1.01
Tactical if someone want to try them -

Code: Select all

Check Extensions (pv nodes) = 0
Check Extensions (non pv nodes) = 0
Single Evasion Extension (pv node) = 0
Single Evasion Extension (non pv node) = 0
Pawn Endgame Extension (pv node) = 0
Pawn Endgame Extension (non pv node) = 0
Mobility (Middle Game) = 80
Space = 80
Aggressiveness = 80
Cowardice = 80
Everything else default.
Regards
Dave

Hello Dave!

That is an very interesting idea from you! 8-)

Please test it! (I will test it too). Let me know the result of your test.

Thanks,

BTW: My own EN plus tactical idea would be this setting:

Code: Select all

[OPTIONS]
Mobility (Middle Game)=80
Space=80
Aggressiveness=80
Cowardice=80
Check Extension (PV nodes)=0
Check Extension (non-PV nodes)=0
Single Evasion Extension (PV nodes)=0
Single Evasion Extension (non-PV nodes)=0
My own first test sounds good!

ED.
Peace be with you!

Hi Ed. I am testing in a round robin tourney with Rybka 4, Houdini 1.02, Fire 1.3, Ivanhoe 55mU, and Stockfish 1.8 at 40/5. So it takes a lot of time to draw a definite conclusion. But so far, i am impressed, these settings are leading the tourney. :o

Imagine what the next version of Gargleblaster will do. Is that the new name being considered to replacing the Stockfish name?! It's horrible.

I'd prefer a better name than that...Little Bighorn.
