Expand description

Variants§

§

Discover(N)

§

TreeEdge(N, N, E)

An edge of the tree formed by the traversal.

§

NonTreeEdge(N, N, E)

An edge that does not belong to the tree.

§

GrayTargetEdge(N, N, E)

For an edge (u, v), if node v is currently in the queue at the time of examination, then it is a gray-target edge.

§

BlackTargetEdge(N, N, E)

For an edge (u, v), if node v has been removed from the queue at the time of examination, then it is a black-target edge.

§

Finish(N)

All edges from a node have been reported.
