  • Outer product (aka outer join) of n lists

    I recently wrote a program to automatically solve a category of logic puzzles, alone the lines of 'four men walked into a bar, one who drinks Guinness never pays darts...' The objective is to find a unique combination of attributes - name, age, favorite drink, favorite pub activity etc. I decided on a brute force approach, in which I generate every combination of attributes, apply a set of rules, and then inspect for the one unique solution. My solution starts with producing a list of lists of attributes.
