Graph (discrete mathematics) - Wikipedia
A weighted graph or a network [9] [10] is a graph in which a number (the weight) is assigned to each edge. [11] Such weights might represent for example costs, lengths or capacities, depending on the problem at hand. 展开
In discrete mathematics, particularly in graph theory, a graph is a structure consisting of a set of objects where some pairs of the objects are in some sense "related". The objects are represented by abstractions called 展开
Oriented graph
One definition of an oriented graph is that it is a directed graph in which at most one of (x, y) and (y, x) may be … 展开• The diagram is a schematic representation of the graph with vertices $${\displaystyle V=\{1,2,3,4,5,6\}}$$ and edges
• In computer science, directed graphs are used to represent knowledge (e.g., conceptual graph 展开In a hypergraph, an edge can join any positive number of vertices.
An undirected graph can be seen as a simplicial complex consisting … 展开Definitions in graph theory vary. The following are some of the more basic ways of defining graphs and related mathematical structures.
Graph
A graph (sometimes called an undirected graph to distinguish it … 展开Two edges of a graph are called adjacent if they share a common vertex. Two edges of a directed graph are called consecutive if the head of the first one is the tail of the second one. Similarly, two vertices are called adjacent if they share a common edge (consecutive if the … 展开
