There is a whole mathematics to heuristics. I have Judea Pearl's _Heuristics_ 
on my bookshelf. Honestly though, nobody cares.

It's really not that complicated once you start it on a mathematical footing. 
I doubt that a lot of what people are presently trying to do was envisioned 
when this book was written; but to get it on a mathematical footing, here's 
how. (Spoiler: no code.)

That's the (meta) problem:  nobody cares about making it less complicated, 
they want to solve their little frog pond problem NOW!

I don't know what Michael is trying to do.
