It is still small and easy, but improving in strength. It seems now to be stronger than any OliThink 4.
Any problems with arena should be solved, too.

Hi Oliver,

Still version 5.0.7 downloads on your webpage.

Hmmm... I see 5.0.8, perhaps a cache-problem?

[Marek Soszynski]

Substitute an 8 for a 7 and the downloads work, e.g. http://home.arcor.de/dreamlike/chess/Ol ... .win32.zip

Oliver, Could you make it support Analysis Mode and turn it into a UCI engine?

[OliverBr]

Thanks for the hint. Links are corrected.

UCI and Analyze mode is interesting. I am working on it.

[Tony Thomas]

Is there anyway you can make the hashtable size adjustable? I can only afford about 50 MB per engine.

Thanks

Change macro:
#define HSIZE 0x800000

to be:
#define HSIZE (0x800000>>1)
and you will get 64 MB.

Change macro:
#define HSIZE 0x800000

to be:
#define HSIZE (0x800000>>2)
and you will get 32 MB.

And then recompile

Dann, I dont know how to compile.

You must also change macro:
#define HMASK 0x7FFFFF

to be
#define HMASK (HSIZE-1)

And macro:
#define HINV 0xFFFFFFFFFF800000LL
would have to be adjusted so that the lower bits match HSIZE and all bits larger than HSIZE are set to 1.

If you add UCI, SEE and quiescent checks move generation, then Olithink would really have a great potential.
