Graph theory is a branch of mathematics and computer science that studies graphs—abstract representations of objects and their relationships. It forms the foundation for solving complex problems in algorithms, network analysis, and data structures!
Key Concepts 📜
- Vertices (Nodes): The fundamental units of a graph, representing entities like people, cities, or data points.
- Edges (Connections): Links between vertices, indicating relationships such as roads, friendships, or dependencies.
- Degree: Number of edges connected to a vertex.
- Paths & Cycles: Sequences of edges connecting vertices (path) or forming a loop (cycle).
Applications 🌐
- Networks: Modeling computer networks, social media connections, or transportation systems.
- Pathfinding: Algorithms like Dijkstra’s or BFS rely on graph theory for navigation.
- Data Representation: Efficiently storing and querying relationships in databases.
- Game Theory: Analyzing strategies in board games and decision-making processes.
