Web7 ©Department of Psychology, University of Melbourne Geodesics A geodesic from a to b is a path of minimum length The geodesic distance dab between a and b is the length of the geodesic If there is no path from a to b, the geodesic distance is infinite For the graph The geodesic distances are: dAB = 1, dAC = 1, dAD = 1, dBC = 1, dBD = 2, dCD = 2 … Webgraph H ⊆ G is a 1-factor of G if and only if E(H) is a matching of V. The problem of how to characterize the graphs that have a 1-factor, i.e. a matching of their entire vertex set, will …
