Graph Algorithms in C++: Finding Optimal Meeting Points

Finding the most efficient meeting location on a map is a classic optimization problem with massive real-world applications in logistics, ride-sharing, and network routing. This text-based course guides you through the process of solving this exact challenge by modeling networks as weighted graphs and applying shortest-path algorithms. You will transition from understanding basic graph theory to writing clean, optimized C++ code that calculates the single best meeting point for multiple travelers. Along the way, you will adopt modern C++ practices to ensure your code is efficient, safe, and readable. What you'll learn: 1. Understand the core terminology of graph theory, including vertices, weighted edges, and adjacency lists. 2. Implement Dijkstra's algorithm from scratch using standard C++ containers like priority queues. 3. Model real-world map data as weighted, directed, and undirected graphs. 4. Calculate shortest paths from multiple sources to find the mathematically optimal meeting point. 5. Apply modern C++ features, including type-safe concepts and smart pointers, to manage graph memory safely. 6. Analyze the time and space complexity of your algorithms to ensure they scale efficiently. The course begins with foundational graph concepts and representation techniques before moving step-by-step through shortest-path logic. You will then write and refine a complete C++ program that solves the multi-source meeting point problem. This course is designed for beginner to intermediate C++ programmers who want to learn practical algorithm design. No prior experience with graph theory is required, though a basic familiarity with C++ syntax is recommended.
