Introduction Undirected graphs are an essential component of computer science and graph theory, representing a set of vertices connected by edges without any directionality. One common problem associated with undirected graphs is the counting the number of nodes in a graph whose sum of neighbours is at most K. In computer science, the graph theory field will deal with the connection between the elements in the given matrix. Usually the graphs consists of the elements namely the edges and the nodes. Count the number of nodes in a Graph The Graph that is exclusively used is the undirected graph in ... Read More
Introduction The Minimum Spanning tree and the shortest tree plays a vital role in the field of graph theory to design the networks. While they share similarities as fundamental concepts, their purposes diverge significantly. In this article, we will dive into these two interesting elements within graphs and highlight their differences. MSTs aim at establishing minimal-cost connectivity among all vertices of a graph without loops, while shortest paths target identifying optimal routes between specific nodes in terms of distance or weight accumulation. Difference between Minimum Spanning Tree and shortest Path Graph theory offers various tools for analyzing connections and pathways ... Read More
Introduction Graph homomorphism may be a crucial concept in chart hypothesis and computational science. Within the setting of C dialect, a chart homomorphism may be a mapping between two charts that jam the contiguousness connections between their vertices. It is frequently spoken to as a work that allocates vertices from one chart to vertices in another, whereas keeping up the edges between them. This concept empowers the consideration and examination of basic similitudes and associations between distinctive charts. By executing chart homomorphism in C, software engineers can investigate different applications, such as chart coordinating, chart coloring, and chart isomorphism testing, ... Read More
Introduction Graphs are powerful mathematical structures that allow us to model and visualize relationships between various entities. In computer science, graphs find application in a wide range of algorithms and data structures. One common problem with undirected graphs is determining whether a cycle exists between two given nodes. In this article, we embark upon the journey to unravel this mystery and present an elegant solution using C/C++. Determining cycles within an undirected graph is vital in various applications where connectivity matters. Undirected Graphs is determining whether a cycle exists between two given nodes Unweighted bidirectional (or undirected) graphs consist of ... Read More
Introduction Graph theory is a fundamental field in computer science, allowing us to study and visualize relationships between objects or entities. One important aspect of analyzing graphs understands the sizes of components or connected subgraphs within the network. In this article, we will explore how to construct a graph from component size for each node using C++ code. In graph theory, a component refers to any connected subgraph where there exists some path between any two vertices within that subgraph. It helps depict clusters or groups of interconnected nodes within the entire graph structure. A Graph from size of components ... Read More
Introduction Graph traversal could be a principal operation in computer science that includes going by all nodes of a graph. In certain scenarios, it may be fundamental to navigate the graph in the lexicographical order of nodes, which suggests going by the nodes in climbing numerical order. In this article, we'll investigate two distinctive approaches to performing a lexicographical DFS traversal of a graph utilizing the C language. These approaches point to creating the same correct yield while giving elective executions and viewpoints. They offer an establishment for understanding a wide extent of graph-related issues, empowering productive investigation, and analysis ... Read More
Introduction Finding the smallest set of vertices to visit all nodes in a graph could be a crucial issue in graph hypothesis. It has practical applications in different areas, counting network optimization, directing algorithms, and task planning. In this article, we are going investigate three diverse approaches to illuminate this problem: Depth-First Search (DFS), Breadth-First Search (BFS), and Depth-First Traversal with Backtracking. We are going give point by point clarifications, code usage within the C language, and algorithmic steps for each approach. Also, we'll illustrate the utilization of these approaches with a test graph to guarantee that all three strategies ... Read More
Introduction The number of ways to reach the beginning hub after traveling through precisely K edges in a total chart can be calculated utilizing different approaches within the C dialect. One approach is to utilize brute constrain recursion, where we investigate all conceivable ways. Another approach includes energetic programming, where we store and reuse halfway comes about to dodge excess computations. Moreover, a numerical equation exists to specifically compute the number of ways based on the number of hubs and edges. These strategies give effective arrangements to decide the check of ways driving back to the beginning hub in a ... Read More
Introduction Finding the primary undeleted integer from a given extend in a detached graph after performing multiple queries may be a challenging issue in graph theory. In this article, we investigate the errand of distinguishing the primary undeleted numbers and give two approaches to fathom it utilizing C++. Each approach offers a diverse point of view and utilizes distinctive calculations and data structures. The problem includes developing a graph, checking certain nodes as deleted, and after that deciding the primary undeleted numbers inside an indicated extend. The graph represents associations between nodes, and the deleted nodes are those that have ... Read More
