Computing median and antimedian sets in median graphsBalakrishnan, Kannan ...Mediana (antimediana) profila ▫$\pi = (u_1,...,u_k)$▫ vozlišč grafa ▫$G$▫ je množica vozlišč ▫$x$▫, ki minimizirajo (maksimizirajo) oddaljenost ▫$\sum_i d(x,u_i)$▫. Oblikovana sta algoritma za ... medianske grafe ▫$G$▫ zahtevnosti ▫$O(n \; {\rm idim}(G))$▫, kjer je ▫$n$▫ red grafa in ▫${\rm idim}(G)$▫ izometrična dimenzija ▫$G$▫. Prvi algoritem izračuna medianske množice profilov in je v praksi pogosto hitrejši kot drugi algoritem. Slednji algoritem dodatno izračuna antimedianske množice ter funkcije oddaljenosti in deluje na poljubnih delnih kockah.Source: Algorithmica. - ISSN 0178-4617 (Vol. 57, no. 2, 2010, str. 207-216)Type of material - article, component partPublish date - 2010Language - englishCOBISS.SI-ID - 15477849
