Digraph walk, path, circuit

  1. Dec 17, 2012 #1
    1. The problem statement, all variables and given/known data
    Given the graph, determine if the following sequences form a walk, path and/or a circuit.

    1. a, b, c, e
    2. b, c, d, d, e, c, f
    3. a, b, c, f, g, a
    4. b, c, d, e


    2. Relevant equations



    3. The attempt at a solution
    1. It's not possible for the vertices to form a walk, path, or a circuit in this configuration. There is no relation from c to e.
    2. walk
    3. walk, circuit
    4. walk, path

    Are these correct, or am I missing something. Thanks for any suggestions.

    You should probably give the definitions of 'walk', 'path' and 'circuit' for a directed graph.
