WebFeb 21, 2024 · This sorting algorithm should be a comparison sort; otherwise, the lower bound may not be valid. Unfortunately, without knowing the sorting algorithm, it's difficult to point to specific inputs that trigger the worst case. Some sorts, such as quicksort and mergesort, are best-case Θ(n log n). WebGraham scan is an algorithm to compute a convex hull of a given set of points in O ( n log n) time. This algorithm first sorts the set of points according to their polar angle and scans the points to find the convex …
WebGraham scan — O ( n log n) A slightly more sophisticated, but much more efficient algorithm, published by Ronald Graham in 1972. If the points are already sorted by one of the coordinates or by the angle to a fixed vector, then the algorithm takes O ( n) time. Quickhull Created independently in 1977 by W. Eddy and in 1978 by A. Bykat.
