Adjacency-Adjacency refers to the relationship between vertices directly connected by an edge. For example, if vertex A is connected to vertex B by an edge, then A and B are considered adjacent. Path-A path in a graph is a sequence of vertices connected by edges. It represents a route or...

A library to simulate DFAs and Probabilistic DFAs using context switching. This library provides a way to build and define the behavior of a graph. The client is able to define the function each vertex and edge of the graph make and how the graph transitions from one (the first valid edg...
The typeMutablerepresents a directed graph with a fixed number of vertices and weighted edges that can be added or removed. The implementation uses hash maps to associate each vertex in the graph with its adjacent vertices. This gives constant time performance for all basic operations. ...
There can be multiple edges between two vertices.(两个顶点之间可以有多条边) Edges are directed. -> identifies the directions of edges. Edges can be traversed in either direction.(边是有方向的) An edge is identified uniquely with a source vertex, an edge type, a rank value, and a destina...

The three vital components used to model data in this format are nodes, edges, and properties. Nodes Objects or instances are represented using a node. Conceptually, nodes are the equivalent of a row in a relational database and act as a vertex within a graph. Grouping a node is simply ...
A graph may be undirected, meaning that there is no distinction between the two vertices associated with each edge, or its edges may be directed from one vertex to another; see Graph (discrete mathematics) for more detailed definitions and for other variations in the types of graph that are ...
