  • One more geodesic graph 

    Grinbergs, Emanuels (2013-12-17)
    In this note, written in Latvian, a way to build geodesic graphs, graphs with unique shortest path between every two vertices, is considered. Geodesic graphs are trees, odd cycles, and nontrivial example, the graph of ...
  • Geodesic graphs
