HISTORY OF SUPERGRAM
Version 1.00 January 1988
Small C program written to teach myself the C language. It ran under
UNIX and did a brute-force search using the lexicon in /etc/words. Printed
out all collections of English words that formed anagrams. No other refinements.
Version 2.00 March 1989
Completely recoded in BBC BASIC on an Arthur Archimedes. Had some understanding
of word frequencies and a few specialist dictionaries. Kept best scoring
words in buffer.
Version 3.00 January 1990
Large sections recoded in ARM assembly language for speed. Extra features
added and dictionaries improved.
Version 4.00 April 1990
Adapted to run under RISC OS in a window. The first complete Desktop program
I wrote. Additional improvements. Lots of work on dictionaries.
Version 4.11 August 1991
Minor changes made and released as a freeware application into the Archimedes
world.
Version 5.00 September 1993
Completely rewritten in C with a view to producing a Microsoft Windows
version. Took advantage of what I learnt in my now-completed computer
science degree to completely polish the searching algorithm (which now
runs around ten times faster than version 4 and around 1000 times faster
than version 1 without resorting to assembler). The skills I learnt when
writing Cyber Chess were put to good effect to improve the user interface
Further large improvements to the dictionaries & extra features.
Version 5.10 October 1993
First release of Supergram II.
