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. http://img843.imageshack.us/img843/5686/digraph.png [Broken] 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.
