Business entities handle a large volume of data. Data must be organized for storage.. The concept of Data Structures and Algorithms is pitched in for this purpose. A data structure is employed for purposes beyond merely organizing data. It is used for data processing, retrieval, and archiving as well. Numerous fundamental and sophisticated types of data structures are used by almost all software systems and programmes that have been developed. We must therefore be knowledgeable about data structures.
Graphs
A graph is a collection of vertices (V1, V2,...Vn) and edges (E = E1, E2,....En). Here, the unordered pair of vertices can be used to identify each individual edge (Vi, Vj). If there is an edge whose endpoints are Vi and Vj, then the two vertices Vi and Vj are said to be adjacent. As a result, Vi and Vj are said to link at E.
The following terminologies are used in Graphs:
i) Order of the Graph = The number of vertices in the graph
ii) Size of the Graph = The number of edges in the graph
iii) Degree of a Vertex of a Graph = Number of edges incident to the vertex
Different Types of ...
... Graphs
Null Graph
A null graph is a graph that has no edges.
Trivial Graph
A single vertex graph is known as Trivial Graph.
Non-Directed Graph
Although there are edges in a non-directed graph, they are not directed edges.
Directed Graph
Each edge in a directed graph has a direction.
Simple Graph
A simple graph is one that has no loops and no parallel edges.
Connected Graph
If a path connects every pair of vertices in a graph G, then the graph is said to be linked. Every vertex in the graph must have at least one edge. In order to claim that it is connected to another vertex located on the opposite side of the edge.
Disconnected Graph
If a graph G does not have at least two linked vertices, it is said to be disconnected.
Regular Graph
If all of a graph G's vertices have the same degree, the graph is said to be regular. A graph is referred to as a "k-regular graph" if each vertex's degree equals k.
Complete Graph
A full graph is a straightforward graph with 'n' mutual vertices, and it is represented by the symbol 'Kn'. A complete graph is one in which every vertex has at least one edge with every other vertex. In other terms, a graph is said to be complete if each vertex is connected to every other vertex.
Cyclic Graph
A simple graph is referred to as a cycle graph if all of its edges form a cycle with length n, (n >= 3). A graph is referred to as a cycle graph if each vertex has a degree of two.
Wheel Graph
A new vertex is added to a cycle graph Cn-1 to create a wheel graph. This new vertex, known as a Hub, is connected to every other vertex in Cn.
Acyclic Graph
A graph which is not connected to each other is called an Acyclic Graph.
Bi-Partite Graph
If every edge of E connects a vertex in V1 to a vertex in V2, then G = (V, E) with vertex partition V = "V1, V2" is referred to as a bipartite graph. A Bipartite graph typically consists of two sets of vertices, let's call them V1 and V2, and if an edge is constructed, it should link any vertex in set V1 to any vertex in set V2.
Complete Bi-Partite Graph
When every vertex in partition V = "V1, V2" of a bipartite graph "G," G = (V, E), is linked to every vertex in partition V2, the graph is said to be complete. Each vertex from set V1 and each vertex from set V2 are typically connected in a full bipartite graph.
Star Graph
An n-vertex star graph is a complete bipartite graph of the form K1, n-1. If there is just one vertex in the first set and every other vertex is in the second set, the star graph is a complete bipartite graph.
