If we are performing a traversal of the entire graph, it visits the first child of a root node, then, in turn, looks at the first child of this node and continues along this branch until it reaches a leaf node.

WebDepth–first search in Graph. A Depth–first search (DFS) is a way of traversing graphs closely related to the preorder traversal of a tree. Following is the recursive implementation of preorder traversal: To turn this into a graph traversal algorithm, replace “child” with “neighbor”. But to prevent infinite loops, keep track of the ... WebOct 10, 2024 · They’re also a good strategic choice for general graph traversals.
