Re: Critter 1.6 released!
Recent changes/additions:
- Automatic detection of SEE4.1 capable CPU. Both SSE4/non-SSE4 codepaths are now compiled in a single executable and chosen dynamically at runtime.
- Large pages suppport. This requires sufficient user privileges and right OS settings.
- Own book is automatically turned off when analysing.
- Engine now honors multi-pv even when the root position is a tablebase hit
- Session file now supports IDEA. SF writes are disabled at root when any moves were excluded.
- Session file writes are now protected by OS IPC mechanisms (semaphores/mutexes). Same session file can be accessed concurrenlty by multiple engine isntances without risking corruption (useful when running IDEA)
- Removed UCI option "SF strategy", now its value is hardwired to "depth"
- New UCI option "SF move limit" which disables learning after game has reached given number of moves. When set to 0 this option is ignored.
- New UCI option "SF material limit" (0..32). Disables learning when total amount of material is less than the given amount [Q=6, R=3, B&N=1]. When set to 0 this option is ignored.
- Gameplay related changes:
* Tweaked blocked-pawn recognizer
* Skewer detection in eval
* King safety tweaks
* Pseudo-contempt: slightly increased preference of moves increasing pressure on the opponents king
* slightly increased preference of pawn pushes in semi-blocked positions
* Recognizing more types of drawish endgames
- new console mode commands "sf probe", "sf delete", "sf store" for mainpulating session file entries

Re: Critter 1.6 released!
Code: Select all
critter-16: /lib64/libc.so.6: version `GLIBC_2.14' not found
Fedora 14 is less than two years old.
I'm not a guru about glibc versions, but compiling closed source stuff on an older box is a nice courtesy... Or perhaps this page is useful http://rjpower.org/wordpress/fun-with-s ... not-found/
cheers

Re: Critter 1.6 released!
Running the 64-bit Linux compile in Scid causes termination when tablebases are accessed.
I don't know if this is the same problem that affected the previous Critter: http://www.mail-archive.com/scid-users@ ... 05894.html
