WebJun 16, 2024 · The Depth-First Search (DFS) is a graph traversal algorithm. In this algorithm, one starting vertex is given, and when an adjacent vertex is found, it moves to that adjacent vertex first and tries to traverse in the same manner. It moves through the whole depth, as much as it can go, after that it backtracks to reach previous vertices to … WebThe mutate execution mode updates the named graph with new relationships. The path returned from the Depth First Search algorithm is a line graph, where the nodes appear in the order they were visited by the algorithm. The relationship type has to be configured using the mutateRelationshipType option. can i buy laptop without operating system
