              This project presents an interactive visualization tool for comparing search algorithms in the context
              of package delivery optimization. We implement and analyze six fundamental search strategies: Breadth-First
              Search (BFS), Depth-First Search (DFS), Iterative Deepening Search (IDS), Uniform Cost Search (UCS),
              Greedy Best-First Search, and A* Search. The system models a grid-based city environment with varying
              traffic conditions, blocked roads, and tunnel shortcuts, providing a comprehensive testbed for evaluating
              algorithm performance in terms of path optimality, computational efficiency, and memory utilization.
