This example demonstrates the A* pathfinding algorithm operating on a network of nodes and links within NetLogo. It shows how the algorithm computes the shortest path between a designated start and end node by assigning each node g-cost, h-cost, and f-cost values based on link distances and a heuristic. The implementation uses NetLogo’s breeds, nodes-own variables, and link-neighbors queries to manage open and closed lists, iteratively spreading from the start node until the end node is reached. It then traces the path backward via owner pointers, marking path? nodes, and utilizes constructs like min-one-of and while loops.
