• ### Directed graphs

Directed graphs Connected graph A graph is connected if and only if there exists a path between every pair of distinct vertices; A graph with the vertex and edge set being subsets of the original graph; A connected component of a graph is a maximally connected subgraph of a graph.

• ### Báo cáo khoa học: "A Method for Relating Multiple Newspaper Articles by Using Graphs, and Its Application to Webcasting"

This paper describes methods for relating (threading) multiple newspaper articles, and for visualizing various characteristics of them by using a directed graph. A set of articles is represented by a set of word vectors, and the similarity between the vectors is then calculated. The graph is constructed from the similarity matrix. By applying some constraints on the chronological ordering of articles, an efficient threading algorithm that runs in O(n) time (where n is the number of articles) is obtained. ...

Planarization method s if the graph is nonplanar, make it planar! (by placing dummy vertices at the crossings) s use one of the drawing algorithms for planar graphs e.g., GIOTTO [Tamassia Batini Di Battista 87] Orientation method s orient the graph into a digraph s use one the drawing algorithms for digraphs Force-Directed method s deﬁne a system of forces acting on the vertices and edges s ﬁnd a minimum energy state (solve differential equations or simulate the evolution of the system)

• ### Graph Algorithms, 2nd Edition

Shimon Even’s Graph Algorithms, published in 1979, was a seminal introductory book on algorithms read by everyone engaged in the field. This thoroughly revised second edition,with a foreword byRichard M.Karp and notes byAndrewV.Goldberg, continues the exceptional presentation from the first edition and explains algorithms in formal but simple language with a direct and intuitive presentation. The material covered by the book begins with basic material, including graphs and shortest paths, trees, depth-first search, and breadth-first search.

• ### Báo cáo " Conflicting chip firing games on graphs and on trees "

Chip Firing Games on (directed) graph are widely used in theoretical computer science and many other sciences. In this model, chips are ﬁred from one vertex to all of its neighbors at the same time. The purpose of our paper is to study an extended version of this model, the Conﬂicting Chip Firing Game, by considering that chips can be ﬁred from one vertex to one of its neighbors at each time. Our main results are obtained when the support graph of this game is a rooted tree. we show

• ### Báo cáo khoa học: "Dependency Parsing with Undirected Graphs"

We introduce a new approach to transitionbased dependency parsing in which the parser does not directly construct a dependency structure, but rather an undirected graph, which is then converted into a directed dependency tree in a post-processing step. This alleviates error propagation, since undirected parsers do not need to observe the single-head constraint. Undirected parsers can be obtained by simplifying existing transition-based parsers satisfying certain conditions.

• ### Chapter 9 - Graph•

A Graph G consists of a set V, whose members are called the vertices of G, together with a set E of pairs of distinct vertices from V. • The pairs in E are called the edges of G. • If the pairs are unordered, G is called an undirected graph or a graph. Otherwise, G is called a directed graph or a digraph. • Two vertices in an undirected graph are called adjacent if there is an edge from the first to the second.
