Hi. The algorithms in GEOS are almost all ported from the JTS Topology Suite, fyi. The reason for not having explicit documentation for algorithm complexity is time/effort, and difficulty of proving the complexity. In general the algorithms should be roughly O(n log n) (as opposed to the O(n^2)

Hi all, Sorry for disturbing and I hope I am passing through the right channel for my question. If not, please feel free to redirect me! I have been searching in the documentation and elsewhere for information regarding the time complexity of the algorithms of GEOS. More precisely around the c
