We run a comparison shopping site for new and used books

Booksellers give us icky data ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

We use clustering algorithms ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Testing is critical ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

We want to test combinations ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

We want to test permutations ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Math::Combinatorics makes things easy

Iterate through combinations ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Add every permutation ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Plug in the tests ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Tested code means happier users. Yay, testing.
