Extracted text: Problem 4: (Provide derivations of your answer, that is, draw the search tree, and write down the list of visited nodes in order and the corresponding frontier nodes). Execute Tree Search through this graph. Step costs are given next to each arc. Heuristic values are given next to each node (as h = x). The successors of each node are indicated by the arrows out of that node. Child nodes are returned from left to right with an alphabetical and numerical order, i.e., children of S are (A, B), children of A are (A, G1, G2), and children of B are (A,B), in that order. Note: G1 and G2 are different nodes, but they are both goal nodes. S h=20 100 20 В 100 14 h=21 A ) h=24 30 26 G1 G2
