A* Search Algorithm

A-Star-Search-Algorithm-Graph

The A* Search algorithm (pronounced “A star”) is an alternative to the Dijkstra’s Shortest Path algorithm. It is used to find the shortest path between two nodes of a weighted graph. The A* Search algorithm performs better than the Dijkstra’s

Dijkstra’s Shortest Path Algorithm

Dijkstra-Algorithm

Dijkstra’s Shortest Path Algorithm is an algorithm used to find the shortest path between two nodes of a weighted graph. Before investigating this algorithm make sure you are familiar with the terminology used when describing Graphs in Computer Science. Let’s

Graphs are a data structure that can be used in computer science in a variety of context. You can check the following Python challenges which are all being solved using a graph and a short path algorithm, one of the

Air Flight Route Planner

Using a graph to plan a flight route between airports.

For this challenge you will use a graph data structure to create an Air Fligh Route Planner for a fictitious airline company offering flights across Europe. Here is a map showing all the direct flights offered by this airline company:

The Social Network

Six Degrees of Separation The Six degrees of separation is an idea that was originally set out by Frigyes Karinthy in 1929 and that can be applied to Social Networks such as Facebook. It is based on the idea that

London Underground – Journey Planner

The aim of this Python challenge is to investigate how graphs can be used in Computer Science and investigate the key algorithms used when manipulating graphs in Python such as an algorithm to find the shortest path between two nodes

Food Chain Game Using Python
