This is my first time reading about pdqsort. I haven't read through the paper, but it's a neat concept, sort of a hybrid that can reduce to a radix sort-like behavior. The cost is instability and slightly worse behavior for, I suppose, higher-entropy inputs. It's interesting to think that sorting has a maximum "total complexity", distributed across the whole input space. And this hybrid algorithm kind of shapes that distribution, squeezing efficiency out of one part of the space, and into another, more practically meaningful part.
