Ask HN: Which algorithms do you use on a regular basis?

Binary search- to find the file that causing the build to break .

Barrier pattern to deal with threads, although I mostly can let libraries deal with that.

Those are two I can remember using recently. I once worked on a very big graph search problem using A* and some other algorithms. That was fun.

None.

I haven't implemented a single computer science-style algorithm since I graduated. Even the rare times I need one there are perfect (i.e. bug free/edge case free) pre-existing examples available.

This is likely true for the silent majority who are doing CRUD or web development.

Dichotomy search is still by far my most used algorithm. Say you want to figure out why a regression happened between commit 1 and 100, please don't build all versions in sequence :-)

An experimental algo similar to Word2Vec

Another experimental algo which compares rich vectors for similarity which is a variant of an uncentered Pearson Correlation

Really this is more of a question of what domain you work in.

Since most algorithms apply to very specific data and needs of that data to do something.
