I've been working on a hybrid in-place merge sort for a few weeks, using a paper called "Ratio based in-place stable merging" from 2008, and it resulted in a design that's 3-15x faster than inplace_stable_sort and 80-90% of the speed of stable_sort, while using O(1) memory. I have all of the details up on the project page, including C++ code that directly benchmarks and validates against stable_sort.</div><div><br></div><div><a href="https://github.com/BonzaiThePenguin/WikiSort">https://github.com/BonzaiThePenguin/WikiSort</a></div><div><br></div><div>Is there someone in particular I should speak to about it?
