• wf/
  Scott Turner's program to generate word searches. In C. This code does not attempt to pack tightly.
• wsfind/
  Wordsrch in this directory generates word search blocks; wsfind searches them. This was code by Dave Regan which I heavily modified to use the DAWG data structure, and speed up considerably. (45 minutes became 45 seconds!)
  The file wsfind.c in here is, I think, a later version than ws-find.c
• wordsearch/
  This is Dave Regan's much newer version of the code above, with a web front end added. (The wordsrch.c code is inside the SupportBin subdirectory, as it is "support code" for the cgi front-end)
• wordsearch_baker/
  Steve Baker's code, in C⁺⁺. This program does attempt to maximise overlap between words and thus keep the grid as small as possible. However it comes with some heavy warnings about how it might run forever, and he suggests killing the program after a minute and tweaking the wordlist if it hasn't finished by then!
• potm/crozzle/
  Fit a list of words into a 20x20 area, with as much overlap as possible.
  This is not a word search generator (it's actually more of a crossword generator), but if some of the input words it is given were reversed left-for-right, this would be a very good starting point for a maximally dense word search puzzle. The leftover squares need only be filled in with dummy letters to finish off the puzzle. The only limitation on this variation is that the crozzle problem does not allow words to be placed diagonally.
