WebNow, we can construct an Hamiltonian path (not cycle) where each vertex "beat" the adjacent vertex on the right (and so the graph indeed as a corresponding directed edge). If we can "line up" the vertices in such way then it corresponds to Hamilonian path. Start with a single vertex - a path of length 1. http://dictionary.sensagent.com/tournament%20graph%20theory/en-en/ dr chisick winnipeg https://hypnauticyacht.com
