Algebraic Crossword ScriptThis is an implementation of Adam Rosenfield's python script for "algebraic crosswords."
It finds all crossword entries in our database which would continue to be words when substituting the substring FROM for the substring TO. Only words which contain FROM in them are considered.
Both FROM and TO can be empty strings. If FROM is the empty string, then TO is added at each position in the string to test for a word. If TO is the empty string, then the FROM string is simply deleted.
Try out a few examples to see how it works. Have fun!
