The Path Planning algorithm can be viewed as a greedy algorithm because it always chooses the closest vertex in V - S to add to S. //insert all vertices into priority queue //Extract-min (first extraction is simply s) //for each neighbor //RELAX(u,v,w) //update label of neighbor, //decrease-key v.d in priority queue Fibonacci Heap – O(|V|log|V| + E) time Uses map from SLAM, Goal from Task Manager, calls decision-maker
