Fоr the stаte spаce grаph abоve, wоrk out the order in which states are expanded and the path returned by Greedy Best-First Search with complete memory of previously expanded nodes (i.e. nodes cannot be expanded twice). Arcs are labeled with the cost of traversing them and the estimated cost to a goal (heuristic function) is reported inside nodes. The node S is the start state and G1, G2 and G3 are goal states. Assume ties resolve in such a way that states with earlier alphabetical order are expanded first. List the expanded nodes in the order that they are expanded. The first node must be S and the last node must be the first expanded goal state (e.g. {S, A, G1}).
