Ask HN: What is new in algorithms and data structures these days?
It's not particularly new, but recently I've been involved a lot with solving large combinatorial optimization problems<p><a href="https://en.m.wikipedia.org/wiki/Combinatorial_optimization" rel="nofollow">https://en.m.wikipedia.org/wiki/Combinatorial_optimization</a><p>Algos to solve those both exact methods and heuristics are super useful in real world applications, and very underappreciated by the HN crowd IMO.
