Route solving
Dijkstra on a static graph across 50+ nodes. Real delivery routing needs live traffic and time windows, which turns it into a different problem entirely.
Overview
A C++ management system built directly on the data structures that make it work: graphs for the delivery network with Dijkstra for shortest-path routing, AVL and BST trees for indexed lookups, and linked lists for order queues.
