UNIT 5 - GRAPHS The Graph ADT Introduction Definition Graph
Graph is a non linear data structure; A map is a well-known example of a graph. The cities are connected via roads railway lines and aerial network.
A DYNAMIC DATA STRUCTURE FOR PLANAR GRAPH EMBEDDING
We consider only planar finite undirected and directed graphs without self-loops and without isolated vertices. We allow parallel edges between two vertices.

Data Structures for Node Connectivity Queries
For a set S ? V of terminals we say that a graph is k-S-connected if ?(s t) ? k for all s
Graph neural networks: A review of methods and applications
Graphs are a kind of data structure which models a set of objects building a fully-connected “word” graph for text or building a scene.
Efficient data structures for dynamic graph analysis
In undirected graphs edges are unordered pairs of vertices and ordered pairs in directed graph. The adjacency list of an undirected vertex is then defined as

CSE373: Data Structures & Algorithms In directed graphs (sometimes called digraphs) edges have a direction ... A graph does not have to be connected.
Contracting a Planar Graph Efficiently
We present a data structure that can maintain a simple planar graph under edge detection 2-edge connectivity
Improved Deterministic Algorithms for Decremental Reachability and
The data structure is based on a novel representation of a strongly connected graph which might be of independent interest.
