WebJun 8, 2024 · Graph traversal Graph traversal Breadth First Search Depth ... Depth First Search is one of the main graph algorithms. ... Depth First Search will also find the shortest paths in a tree (because there only exists one simple path), but on general graphs this is not the case. WebEach traversal of the graph will necessarily maintain a list of all the nodes traversed from start to the current node. This defines the path. There will be storage to contain the completed paths which contains zero or more paths representing traversal from the start node to an exit node. Algorithm. Current node is the start node.
