Plisk 024 release

Post by vladstamate »

Hi all,

I've made available a new Plisk release (024o). This version plays stronger than Plisk023h. The STS tests results have improved from 583/1000 (in 023h) to 596/1000 so an increase of 13/1000.

Among the changes I have done is improved the search such that Plisk now searches deeper and faster. For example, thanks to the Stockfish team I managed to replace my delta pruning in QS nodes (once per node) with a futility prunning per move in QS node based on approximate material gain. The LMR algorithm has had some changes too, to provide more aggressive pruning. To balance that, I reduced pruning done in PV nodes in both normal search as well as QS.

Another important thing is that I made Plisk able to read Polyglot opening books and from now on, Plisk will be released with a Polyglot book. Plisk can also be used to manage books: it can create books, merge books, print statistics as well as print moves given a fen position. The readme explains how this is done.

You can get Plisk from here:

There are binaries provided for Win (32 and 64 bit), Linux (32bit) and MacOSX (Snow Leopard).

Regards,
Vlad.

Mersi Vlad ,

Pliskul este acum clar mai bun decat vechea creatie a lui Andrei Fortuna (concitadinul meu ) - Freyr. Inca un pic si va fi la nivel de maestru !

Cu stima,
Silvian

Hi Vlad,
unfortunately the OS X binary does not run on the old Leo (10.5.8).

Code: Select all

$ ./plisk_osx 
dyld: unknown required load command 0x80000022
Trace/BPT trap
In this thread was a little discussion about HOWTO create a Mac version of Spark 0.4 for OS X 10.5 & 10.6. Could you please compile a 64-bit Plisk for OS X 10.5 too?

Thank you very much,
Max
