Abstract:Skoraj medianski grafi in semi-medianski grafi sta dve naravni posplošitvi dobro znanega razreda medianskih grafov. V članku dokažemo, da je semi-medianski graf skoraj medianski, če in samo če ne vsebuje konveksnega cikla dolžine večje kot štiri.

Title:Karakterizacija skoraj medianskih grafov
Abstract:Almost-median and semi-median graphs are two natural generalizations of the well-known class of median graphs. In this note we prove that a semi-median graph is almost-median if and only if it does not contain any convex cycle of length greater than four.
