WebbThis paper considers the following problem: Given a set G of n (possibly intersecting) line segments in the plane, preprocess it so that, given a query ray ρ emanating from a point p, one can quickly compute the intersection point Φ … Webbthe ordinary simplex range searching problem, even if we are not restricted to use \multilevel data structures." Not only that, but we also show that the lower bound also generalizes to geometric search structures based on Fr echet distance: preprocess a set of npolygonal curves of complexity tsuch that given a query polygonal curve how to run github
