Also Read: Depth First Search (DFS) Traversal of a Graph [Algorithm and Program] A Graph G = (V, E) is a collection of sets V and E where V is a collection of vertices and E is a collection of edges. The aim of BFS algorithm is to traverse the graph as close as possible to the root node. Approach: We have already seen how to solve this problem using dynamic-programming approach in this article. The algorithm you wrote is a variant of Bellman-Ford Algorithm.. Shortest_Path_Faster_Algorithm is an improvement of the Bellman-Ford algorithm(as well as yours). BFS in c++ . Implementation in C #include <stdio.h> #include <stdlib.h> #include <stdbool.h> #define MAX 5 struct Vertex { char label; bool visited; }; //queue variables int queue[MAX]; int rear = -1 . C. Heap. Traversal can start from any vertex, say V i. V i is visited and then all vertices adjacent to V i are traversed recursively using DFS. The only catch here is, unlike trees, graphs may contain cycles, so we may come to the same node again. Step 1: Open sublime text. Creating array of pointers in C++. !
