Jan 7, 2025 · Learn about graphs, paths, cycles, connectivity, and more in data structures and algorithms. Understand basic definitions, graph representations, and examples of graph algorithms such as traversal and shortest paths. Dive into connectivity, components, and graph properties like planarity and coloring.

The document discusses graph data structures and algorithms. It defines key graph terms like vertices, edges, adjacency, paths and cycles. It also describes different graph types and two common representations: adjacency matrix and adjacency list. Finally, it explains two graph traversal algorithms - depth-first search and breadth-first search.

Apr 5, 2019 · Data Structures - Graph • Graphs are simply a collection of nodes (points) and edges connecting the nodes. • Typical notation lookslike this G = { N, E }. • G = the graph. • N = node set • E = edge set • Nodes represent items under consideration - can be anything. • Edges represent relationships between the items - can be anything.

37 Data Structures for Dijkstra’s Algorithm |V| times: Select the unknown node with the lowest cost findMin/deleteMin O(log |V|) |E| times: a’s cost = min(a’s old cost, …) What data structures do we use to support these little snippets from Dijkstra’s? Priority Queue and a …

DATA STRUCTURES AND ALGORITHMS CHAPTER 07- GRAPHS 1 WHAT IS A GRAPH? A graph G = (V,E) is composed of: V: set of vertices E: set of edges connecting the vertices in V An edge e = (u,v) is a pair of vertices Example: a b c d V= {a,b,c,d,e} E= {(a,b),(a
