| 41. | When required to have a single exit, flow graphs have two properties not shared with directed graphs in general.
|
| 42. | The latter are bidirected graphs, not directed graphs ( except in the trivial case of all positive signs ).
|
| 43. | The remainder of this article focuses on the more difficult problem of determining pairwise reachability in a directed graph.
|
| 44. | Undirected graphs often use the latter convention of counting loops twice, whereas directed graphs typically use the former convention.
|
| 45. | A query plan is a directed graph where the nodes are operators and the edges describe the processing flow.
|
| 46. | When the input and output alphabet are both, one can also associate to a Mealy Automata an Helix directed graph.
|
| 47. | Think of the components as nodes of a directed graph : each one has a specific task on the data.
|
| 48. | Transitive subgroups of S _ n form a directed graph : one group can be a subgroup of several groups.
|
| 49. | If the relation is interpreted as a directed graph, this is the same thing as the transpose of the graph.
|
| 50. | The Floyd Warshall algorithm can be used to find the shortest paths between all pairs of vertices in weighted directed graphs.
