Solver program for alphametic puzzles
This is a program to solve puzzles like the famous SEND + MORE ------ MONEY where letters have to be replaced by digits injectively, i.e. different letters by different digits. Obviously this can be generalized to arbitrary radices instead of 10. Furthermore there should be far more operations allowed than "+". This application implements the four basic operations +, -, * and / and leaves room for more, if wanted.
