Logic Helper

Solve logic-grid puzzles — the "who published which book in which year" kind. Enter each category's items into the grid, paste in the clues, and Logic Helper turns them into solver statements and deduces the completed grid.

Statement syntax:
either([350,bifid],[2006,frappgirl]);
Each element on left side is matched to an element on the right side
equal(playfair,[2008]);
The element on the left side matches all elements on the right side
not(vigenere,[2004]);
The element on the left side does not match all elements on the right side
delta(playfair,2003,0,>,Cat1);
Based on column Cat1, the first is greater, smaller or equal to the other element by 0
distinct([275,2003,2005,r&mrowe,black jeep]);
None of these items are in the same row or column
