Problem 1 Search (10.5 credits)
In the following tasks we search for a path from node A to node G , if not stated otherwise. If multiple nodes can be
explored next, alphabetic ordering should be used as the tie breaker, e.g., if B and C are added to the frontier, B is
added first.
On each of the following graphs we apply breadth-first (BFS) and depth-first (DFS) Graph-Search. Find out which
graphs are explored by each algorithm in the order A , B , C , D .
