## Exploring Graph Search Algorithms: BFS and DFS In this educational resource, we will explore two fundamental graph search algorithms: Breadth-First Search (BFS) and Depth-First Search (DFS). These algorithms are applied to the graphs shown below. ### a) Breadth-First Search (BFS) **Graph Description:** The graph consists of six nodes labeled \( r, s, t, u, v, \) and \( w, x, y \). Each node is represented by a circle. The graph has connections (edges) between the nodes. - Node \( s \) is the starting node with a value of 0. - Nodes \( r, t, u, v \) initially have a distance of infinity (\(\infty\)). **Graph Connections:** 1. \( s \) is connected to \( r \) and \( w \). 2. \( w \) is connected to \( x \). 3. \( x \) is connected to \( t \) and \( y \). 4. \( y \) is connected to \( u \). 5. Edges between nodes display potential paths for traversal. ### b) Depth-First Search (DFS) **Graph Description:** The graph consists of five nodes labeled \( u, v, w, x, \) and \( y, z \). Each node is represented by a circle. The graph shows directional paths indicating the order in which nodes can be accessed. - Node \( u \) is shaded and marked as the starting node. **Graph Connections:** 1. \( u \) is directed towards \( x \). 2. \( v \) has bidirectional edges with \( y \) and connects to \( w \). 3. Both \( y \) and \( z \) are possible endpoints for exploration initiated from \( v \). ### Explanation: - **BFS** explores the graph level by level starting from the initial node, ensuring the shortest path in an unweighted graph is found first. - **DFS** dives deep into the graph, exploring a path fully before backtracking and proceeding to the next path. These algorithms are essential in finding routes, solving puzzles, or in applications requiring systematic data exploration. Understanding their step-by-step execution helps in visualizing the approach of breadth-wise versus depth-wise exploration.
