Transcribed Image Text:### Understanding Graphs: Weighted Graph Example
Welcome to our educational page dedicated to understanding graphs, specifically weighted graphs. In this example, we will explore the structure and components of a weighted graph, which is commonly used in fields such as computer science, networking, and transportation planning.
#### Image Description
The image above displays a weighted graph. A weighted graph is a type of mathematical graph in which each edge (connection between two vertices, or points) has a numerical value (weight) associated with it. These weights can represent various things, such as distances, costs, or times.
#### Key Components of the Weighted Graph:
- **Vertices (Nodes):** Points where edges meet. In this graph, the vertices are labeled as A, B, C, D, and E.
- **Edges (Connections):** The connections between vertices. Each edge is represented by a line connecting two vertices.
- **Weights:** Numerical values assigned to the edges. These values are usually written along the edges. In this graph, the weights range from 2 to 9.
#### Detailed Explanation of the Graph:
1. **Vertices:**
- A, B, C, D, and E are the vertices of the graph.
2. **Edges and Weights:**
- Edge AB has a weight of 2.
- Edge AC has a weight of 4.
- Edge AD has a weight of 8.
- Edge AE has a weight of 5.
- Edge BC has a weight of 7.
- Edge BD has a weight of 5.
- Edge BE has a weight of 6.
- Edge CD has a weight of 3.
- Edge CE has a weight of 2.
- Edge DE has a weight of 9.
#### Applications:
Weighted graphs are used in various applications:
- **Network Design:** Optimizing paths for minimal cost or maximum efficiency.
- **Transportation:** Planning routes and understanding the shortest or safest paths.
- **Project Management:** Determining critical paths in task schedules.
Understanding weighted graphs is crucial for solving real-world problems that require efficient decision-making based on multiple factors. This example helps illustrate the basic components and usage of weighted graphs.
