Hakkapeliitta 3.0 release

[Bloodbane]

Hi all. It's time for a new release of Hakkapeliitta. Below you can see the result of a few 60s+0.05s games which should give you some idea about the expected strength level of 3.0.

Code: Select all

Rank Name                Elo    +    - games score oppo. draws
   1 Hakkapeliitta 3.0   111    6    5  5055   79%  -111   21%
   2 Hakkapeliitta 2.0  -111    5    6  5055   21%   111   21%

So a nice 220 elo increase. I really hope it stays that way in LTC games. Anyways, there are a huge number of changes from 2.0 so I won't be even trying to list them all, with the exception of adding pondering as that is a user feature, rewriting everything to fix several stupid design decisions (the main one was not being able to check easily if a move is a check before making it), and fixing several big bugs which caused some time losses before. I didn't add large page support like I planned as that is way too much pain to deal with, at least for now. The next version will have multithreading, support for "searchmoves" and "multipv", and it will be at least 50 elo stronger single-threaded as well. However, since multithreading is not easy, the new version won't probably be released for a while.

You can find Hakkapeliitta in the address below:

Only Windows binaries are provided (w32 should work on XP as well) since my Linux virtual machine is acting funny at the moment, but I've added a makefile which can be used to produce binaries on other platforms as well, hopefully (do note that -march=native is used, making binaries compiled on one machine architecture useless to any and all machines with an older architecture).

The binaries provided are quite big, but with dynamic linking, clever compiler options and UPX you can bring the executable size to about 68KB if you really, really want to.

If there are any problems, please let me know.

Nice. Fantastic improvement!

Big advances!

Thanks for adding the makefile. Hakkapeliitta 3.0 runs well under Linux Mint on my server. Perhaps too well . It beat Gaviota 1.0 4cpu in a ten game match @2'+1" tc (4-2-2)

Hi,

Many thanks for this release ! It will play in my leagues, in the "Botvinnik" league : with the elo increase you mentionned, it will qualify easily in the superior league !

Neither exe runs on my Windows 8.1 machine. The message simply is "this app can't run on your PC. To find a version for your PC, check with the software publisher"

In my Windows 8.1 x64 laptop works fine. Typical reason for this error is having an incompatible processor. May be the compilation is for more advanced cpu?

I tried a little match of 10 seconds plus 0.02 and Hakkapeliitta wins Andscacs 081

Andscacs 0.81 vs Hakkapeliitta 3.0 x64: 77 - 85 - 43 [0.48] 205

Could you provide a little bit more details about your system, like what hardware you are using, and is your version of Windows 8.1 32 bit?

It is Windows 8.1 64-bit, and AMD FX-8350. Perhaps your compiles are Intel-only ?
