Graph Structures

Theano Tutorial

Graph Structures Debugging or profiling code written in Theano is not that simple if you do not know what goes on under the hood. This chapter is meant to introduce you to a required minimum of the i...

Everything about Graph Data Structure : An Overview Photo by Guille Álvarez on Unsplash Below is a Graph Data Structure A graph consists on Vertices (also called as nodes) and Edges. Claps and Follow...

Graph Theory

Python in Plain English

1\. Introduction to Graph Theory 1.1. Definition and Terminology Graph theory is a branch of mathematics that studies the relationship between pairs of objects. In the context of computer science, th...

Graphs

Codecademy

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…
