Application of sorting algorithms for convex hull determination

Mihaela Todorova, Stoyan Kapralov, Valentina Dyankova


The proposed research explores the possibilities of applying some base algorithms for sorting to the process of finding a convex in order to optimize the time indicators of this process. A comparative analysis of the time characteristics has been performed using different time approaches in Graham’s algorithm. The empirical results obtained have been used as a basis for building a pattern model of the process of finding a convex hull. It performs point sorting by a given criterion and finds a convex hull on a two-dimensional set of points. For this model, a visualization module has been developed that can be used as a learning environment in the courses of computing and complexity of algorithms.
