Description
The Super Micro chess engine series started as a further
shrinking and enhancement of the amazing Micro-Max
chess engine developed by H.G.Muller (http://home.hccnet.nl/h.g.muller/max-src2.html),
which in less than 1200 characters included the
engine and even the user interface with legality
move check.
The current "shrinking level" of this
version is around 670 bytes. Yes, in 670
characters, all ascii printable and including
spaces and new-lines, there is the complete source
of a chess engine implemented in a general purpose
language, all included. It is so small that the
program icon even in its smallest version is
many bytes bigger than the program source, and it
is even possible to print it on a post stamp (lol)!
Later on this version has been extended to allow
playing with full FIDE rules, meaning including
the management of en-passant, castling and under
promotion. This new version is around 750
characters (35 lines of codes when pretty printed).
With the concepts taken from the "source series", there
has been also released a completely rewritten
version (in assembler) focused on executable size.
Currently full FIDE version with a nice color
"point and move" (slightly bigger)
interface fits in 583 bytes, while the
"mini" version is just 455 bytes! And it is
not so easy to beat them!
As far as I know, these are the world smallest
chess programs available, both in source size
and execution size... and optimization might
continue! :)
The last nice addition to the set is a ZX81-1K
version, that is able to play both colors, with all
the FIDE rules and with different level of
strenght.
