Okay, maybe I was a bit harsh, but it definitely doesn't pop up as often as deep learning and statistical machine learning. For those who wish to get deeper into this, I highly recommend Optimization over Integers by Bertsimas and Weismantel.
Obviously not everything will be easy to map into a classic optimization problem. And you may have a heuristic approach that is better for a problem. But the general solvers out there have gone a long long way.
Otherwise, the basic underlying algorithms are all the same, as in the textbook: branch-and-bound and so on.
