Hi Filip, thank you for the information. The implementation of the O(n^2) edge-finder of [Baptiste,Le Pape, Nuijten] seemed to us easier to implement than the O(n log n) algorithm of Vilim, which uses binary trees. So we chose the O(n^2), as it was the first propagator we were implementing.
Maybe we should try to implement that O(n log n) version. Cheers Jan Filip Konvička napsal(a): > > > Hi Jan, > >> thank you for the reply.
