Combinatorial testing is an important area to apply combinatorial algorithms. [0] is a website to start with Combinatorial Test Case Generation.

Obligatory mention of Wilf's "generatingfunctionology" that is also an excellent book [1].

Aw, I wish they made an edition to be read by humans.

I notice that when I open this PDF using Preview on my Mac, I can't select and copy text. I assume this is because (1) text selection is disabled somehow, or (2) the document is just a collection of images. Does software exist that can convert a printed page with a lot of math notation into a truly digital document?

OCR?

is it common to implement these algorithms yourself anymore?
