Ancient olithink fossils
Posted: Tue Nov 03, 2020 7:18 pm
Found them on my old chess analysis project backup CD.
I have some more somewhere, but it might take a while to find them.
Oldest one is Olithink 2.2.1 from 20 years ago.
Code: Select all
OliThink, Version 2.0s (c) 1998 // NAME AND E-MAIL DELETED TO AVOID WEB CRAWLERS.
OliThink is a medium strength chess programm, with an ELO
about 2000. It automatically recognizes Draw by repitition and
50 moves rule and is complete compatible with the standard
interfaces xboard/winboard. It does not use table base.
If you are looking for an aggressiv, fast, but beatable chess programm,
you will be happy with OliThink.
Extract : tar -xvzf olithink.tgz on Linux
: gtar -xvzf olithink.tgz on commercial Unix platforms
: pkunzip -d olithink.zip on dos/windows
Compile : make
Interface : xboard/winboard or compatible (all functions implemented)
: local: xboard -fcp ./olithink
: ICS: xboard -zp -ics -icshost chess4u.com -fcp ./olithink
All (!) relevant xboard/winboard menus and options should work,
including:
'Show Thinking' , '-thinking true'
'Move Now'
'Retract Move'
'Hint'
'Book'
'-sd #' (search depth)
Additional command line options without the interface:
-h # : hashsize (if #<=128 it will be in MB) (default 4 MB)
-t : do not ponder with permanent brain
-p : show principle variant
-s # : search depth # plies
-r # : random moves strength # (recommended <10)
-d : display ASCII board
-n : don't use opening book
-k : do not kibitz forced win
-w : whisper actual eval
-z : display opening books in e2e4-format
-c : save oponents wins
-b # pgn: create book for white with max ply # and file pgn
e.g. './olithink -b 20 Book4.pgn'
e.g. './olithink -z -b 60 Book4.pgn > eco.txt'
