Adjacency List with String vertices using C++ STL

Posted on

Hello people..! This is a special extension for my discussion on Graph Theory Basics. Here, I give you the code for implementing the Adjacency List using C++ STL where each vertex is a string instead of and integer. This code has been requested many times, so I decided to create a separate page for it. […]

Prim’s Algorithm

Posted on

Hello people…! In this post, I will talk about the Prim’s Algorithm for finding a Minimum Spanning Tree for a given weighted graph. It is an excellent example of a Greedy Algorithm. It is very similar to Dijkstra’s Algorithm for finding the shortest path from a given source. This is my first post regarding the […]

Bellman Ford Algorithm

Posted on

Hello people…! In this post I will talk about another single source shortest path algorithm, the Bellman Ford Algorithm. Unlike Dijkstra’s Algorithm, which works only for a graph positive edge weights, the Bellman Ford Algorithm will give the shortest path from a given vertex for a graph with negative edge weights also. Due to this, […]

Dijkstra’s Algorithm

Posted on

Hello, people…! In this post, I will talk about one of the fastest single source shortest path algorithms, which is, the Dijkstra’s Algorithm. The Dijkstra’s Algorithm works on a weighted graph with non-negative edge weights and gives a Shortest Path Tree. It is a greedy algorithm, which sort of mimics the working of breadth first search […]

Depth First Search Algorithm

Posted on

Hello people…! In this post I will talk about the other Graph Search Algorithm, the Depth First Search Algorithm. Depth First Search is different by nature from Breadth First Search. As the name suggests, “Depth”, we pick up a vertex S and see all the other vertices that can possibly reached by that vertex S and […]
