Cryptarithmetic Puzzle Solver

• We stopped the CGI service on December 2020.
  • See statistics to find puzzles with unique solution.
• This program is written in LLP (a Linear Logic Programming language).

I also wrote another cryptarithmetic puzzle solver in C. Source code package is crypt14.tgz (see also README, crypt.c, crypt.h ). This package also includes puzzle generators written in Perl. The followings are generated puzzles.
