Arasan 13.2

[jdart]

Arasan 13.2 is available from http://www.arasanchess.org.

Changes in Arasan 13.2:
1) Fix in search to eliminate some unnecessary re-searches.
2) Fixes to material scoring for unbalanced material positions.
3) Simplified bonus code for Bishop in endgames with pawns on both sides.
4) Revised bonus for trading material when ahead.
5) Misc. scoring fixes, esp. for connected rook on 7th.
6) Utility programs such as makebook now do not create a log file.
7) Another/better fix for UCI output after a quick mate.

For the first time, a pre-built Intel Mac binary is available.

I ran a 400 1:0 game test match on Linux against 13.1, both engines with 2 cores, ponder on, and 13.2 scored +150 -114 =136 (54.5%) or about +30 ELO. Your mileage may vary.

Thanks Jon, I will replace at once 13.1 by this one...Hope this will leave me to win. Have you programmed that into it?

Problems. In my download Arasan for windows 32 does not appear.

Not sure what you mean - it is not in the download page? If so try refreshing the page in the browser (Control-R).

Thanks Jon.

Hi,
It says there that the test suite was last modified a couple of days ago, but Mozilla marks the link as already pressed, does it mean you made changes but kept the name? If so, what changes did you make?
cheers

Thanks for the Mac support.

Hi Jon,

I had an idea in my brain and it would be great if you can support this idea as more or less "pilot project".

Shortly:

You have to fill out a contact form with different questions:

Example: How old are you, how old is your engine, how long you develops Arasan, with a pic from yourself and some easy questions more.

In this form you will find 20 "basic engines I will used". Example: Smarthink, AnMon, Hannibal, Critter and so one ...

Now you can give me 10 of this 20 basic engines. My systems are playing 100 games vs. this 10 engines with 40 moves in 40 minutes. I will create a detail page about Arasan 13.2 with a short text to weaknesses and strengths and the information you sent by mail.

You have the chance to comment my valuation.
ELO will be not important, only with points like this one:

Endgame: **** of 6
Early endgame: ***
Middlegame: ***
Positional strength: ***
Tactical strength: ****

And the text with my impressions about Arasan 13.2.

Games can be replay in a replay zone on my webpage too and download with GUI comments.

What do you think about the idea?
If you like the idea we can start the pilot project and I will develops the webpage about it.

I am very interesting what you think about this idea!

Best
Frank

PS:
If the first results is good, other amteur programmer can fill out the contact form and I do the same for others.

Hi Jon,

perhaps a bad idea, I don't know.
I am thinking that this one can help amateurs to improved here programs a lot.

Perhaps others should also give comments to such an test if a test is ready:

Example:
Clemens Keck wrote to this test:
No Frank, I look a bit in the games and I am thinking the tactical playing strength must be higher as in your table. Example for my opinion ...

Amateurs which have interest to look in the games and to work with the games are welcome. So this work will be never for nothing. And I know the programmers have interest on here developing.

Think so ...

I think the idea is not bad. If I understand you right you want to do a small ratinglist for programmers who are interested. They give some more information and therefore they get support by you and probably more attention by the community. And in times we have hundrets of engines it is not necessary to invest time in dead developements.

Most people don't use 500 Engines. Some informations about the programms would be very useful.

I tried something similar, I rated the UCI engines in different categories.

Nice idea. Do it.

Best,
Alex
