Spanning tree: A spanning tree (T) of an undirected graph(G) is a subgraph which is a tree that includes all the vertices of a graph… Read More
For a connected and undirected graph, a spanning tree of that graph is a subgraph that is a tree and connects all the vertices together.… Read More
Given a 2D array houses[][] consisting of N 2D coordinates {x, y} where each coordinate represents the location of each house, the task is to… Read More
The minimum bottleneck spanning tree in an undirected graph is a tree whose most expensive edge is as minimum as possible. In this article, we… Read More
Given a bi-directed weighted (positive) graph without self-loops, the task is to generate the minimum spanning tree of the graph.Examples:   Input: N = 9, E… Read More
Kruskal’s algorithm for MST  Given a connected and undirected graph, a spanning tree of that graph is a subgraph that is a tree and connects… Read More
Below are the steps for finding MST using Kruskal’s algorithm   1. Sort all the edges in non-decreasing order of their weight. 2. Pick the smallest edge.… Read More
Prerequisite – Spanning Tree Protocol Spanning Tree Protocol (STP) is used to make a loop free network by monitoring the network to track all the links… Read More
There are n cities and there are roads in between some of the cities. Somehow all the roads are damaged simultaneously. We have to repair… Read More
Minimum spanning Tree (MST) is an important topic for GATE. Therefore, we will discuss how to solve different types of questions based on MST. Before… Read More
Reverse Delete algorithm is closely related to Kruskal’s algorithm. In Kruskal’s algorithm what we do is : Sort edges by increasing order of their weights.… Read More
