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). WebJun 13, 2016 · After this you can use Graham's scan or Andrew's monotone chain algorithm —my favourite, both are of O(n log n)complexity. Note that, like @Chill mentioned in comments above, Chan's method is optimal. In practice this method is much faster than applying one of the algorithms to the point set without any filtering.
