Graphs are a way of modeling systems based on a node and edge structure for representing the relationships between items. There are many types of systems and problems that lend themselves to be repres...

Representing Graph Data Structures

Towards Data Science

When you’re representing a graph structure G, the vertices, V, are very straight forward to store since they are a set and can be represented directly as such. For instance, for a graph of 5…

Graphs

Super Study Guide

General concepts Definition A graph G G G is defined by its vertices V V V and edges E E E and is often noted G = ( V , E ) G = (V, E) G = ( V , E ) . The following table summarizes the two main t...

Graphs Data Structure: Depth First Search

Level Up Coding

In a previous blog post we talked about how to apply the Breadth First Search algorithm to the graph data structure. Today, let’s figure out how Depth First Search (DFS) works. DFS is one of the…

Python Structures: Graphs Part II

Python in Plain English

Welcome to part II of my graph series. Here I’ll be explore the nuts and bolts of setting up the two classes (vertex, and the graph) for a graph structure. Now like any good programmer, before we…

Graph Theory Basics

Towards Data Science

In programming and mathematical terms, graph theory is really nothing new, but the implementation and usage of it in code has grown in advances in Machine Learning and AI. One big reason for this is…

Graph Data Structure — Theory and Python Implementation

Python in Plain English

Hi everyone, in previous articles we had the opportunity to talk about widely used data structures like linked lists, queues, stacks, etc. The basic concept behind these data structures is the…

Graph theory

Towards Data Science

Graphs (G) are special data structures that are composed of vertices (a.k.a nodes V) and edges (a.k.a. links E) G(V, E). Edges can be weighted and represent, for example, a distance between cities.

Designing a Graph Data Structure in a Relational Database

Level Up Coding

If you ever wanted to ask me why would you ever want to design a Graph Data Structure in a Relational Database (like MySQL or Postgres), and not use a Graph Database or NoSQL, it would be for a few…

Graphs in Python: Adjacency Matrix

As we all know that Graph is as a kind of data structure that is basically used to connect various elements through a network. In this article , you will learn about how to create a graph using…

Graph Theory — Basic Properties

Towards Data Science

Let’s take a step back in order to take a few more forward in our walk through the basics of graph theory. The previous article in this series mainly revolved around explaining & notating something…

Get started with Graph Theory

Towards Data Science

Graph Theory, in essence, is the study of properties and applications of graphs or networks. As I mentioned above, this is a huge topic and the goal of this series is to gain an understanding of how…
