Graph Traversals Input: A simple, undirected, and connected graph G = (V;E) with jVj= n vertices and jEj= m edges. Objective: Find a traversal path that visits all the vertices of the graph and traverses all the edges of a graph. Remark: Vertices can be visited more than once and edges can be traversed more than once. Amotz Bar-Noy (CUNY) Graph Traversals Spring 2 / Graph Theory and Traversals • Explain why graph traversals are more complicated than tree traversals. An Introduction to Graph Theory A graph G=(V,E) consists of: (a) a non-empty set of vertices V, and (b) a set of edges E between pairs of those vertices. An. Module 8: Trees and Graphs Theme 1: Basic Properties of Trees A (rooted) tree is a finite set of nodes such that Theme 2: Tree Traversals Trees are often used to store information. In order to retrieve such information we need a procedure to visit all nodes of a tree. We describe here three such procedures called inorder, postorder and.

CITS Data Structures and Algorithms. Topic Tree and Graph Traversals. • Tree traversals. • Bredth First Search. • Depth First Search. • Topological Sort. Directed graphs: An edge is traversed only from its origin to its destination. Disconnected . one of its ancestors nor one of its descendants in the traversal tree. Graph Traversals. Page 2. Graph traversal (BFS and DFS). ▫. G can be non- discovery (non-tree) edges: lead to already visited vertices. ▫. The distance d(u). BFS Tree Example. A BFS traversal of a graph results in a breadth-first search tree: 2. 1 s. 1. 2. 3. 3. 3. Can we say anything about the non-tree. Graph Traversals: Depth-First. Assume a particular node has which includes all the nodes of the graph. Such a tree is called a spanning tree for the graph. a. 8. Trees and Graph Traversals | 𝗥𝗲𝗾𝘂𝗲𝘀𝘁 𝗣𝗗𝗙 on ResearchGate | Trees and Graph Traversals | A tree is a connected acyclic graph and a forest consists of. Graph Traversals. • Traversal – how we “visit” the vertices in a graph. • Recall pre-, post-, and in-order traversal of trees. • We will use a generic (abstract ). Graphs. So far we have examined trees in detail. Trees are a specific instance of In general, a graph is composed of edges E and vertices V that link the nodes together. . Results in a forest of trees. Pseudocode: DFS(s) for each vertex u∈V .

Graph Traversals 18 Breadth-First Search • Like DFS, aBreadth-First Search (BFS) traverses a connected component of a graph, and in doing so defines a spanning tree with several useful properties - The starting vertexs has level 0, and, as in DFS, defines that point as an “anchor.” - In the first round, the string is unrolled the length. Graph Traversals Slides by Carl Kingsford Feb. 1, Based on/Reading: Chapter 3 of Kleinberg & Tardos.

February 26, Graph Traversals: BFS and DFS 2 One can also think about BFS not in terms of layers, but in terms of a tree T rooted at s. More speci cally, for each node v 6= s, consider the moment when v is rst discovered by the BFS algorithm. This happens when some node u in layer L.
