Consider the search space below, where S is the start node and G1 and G2 are goal nodes. Arcs are labeled with the value of a cost function; the number gives the cost of traversing the arc. Above each node is the value of a heuristic function. Assume that search algorithms always choose alphabetically when there is a tie, and expand the older node if two nodes are still tied.
A- Give the solution by each one of the following search strategies to reach a goal
state.
