Web15 de feb. de 1996 · Traversal of graphs and digraphs To traverse means to visit the vertices in some systematic order. You should be familiar with various traversal methods for trees: preorder: visit each node before its children. postorder: visit each node after its children. inorder (for binary trees only): visit left subtree, node, right subtree. WebLet G be a simple graph. A spanning tree of G is a subgraph of G that is a tree containing every vertex of G. Theorem 1 A simple graph is connected if and only if it has a spanning tree. Depth-First Search A spanning tree can be built by doing a depth-ﬁrst search of the graph. Start with arbitrarily chosen vertex of the graph as the root. WebBreadth-first search (BFS) is an algorithm for searching a tree data structure for a node that satisfies a given property. It starts at the tree root and explores all nodes at the present depth prior to moving on to the nodes at the next depth level. Extra memory, usually a queue, is needed to keep track of the child nodes that were encountered but not yet … brightxjapan

In an undirected graph, BFS should only produce tree edges and cross edges. Cross edges will always be produced if there are cycles in the undirected graph (i.e. m ≥ n ).
