SOLVED: Consider the state space graph shown below. S is the start stateand G is the goal state. The costs for each edge are shown on thegraph. Ties are resolved alphabetically. The heuristic values foreach state are also included.What nodes are expanded when weapply uniform cost graph search? Please explainWhat nodes are expanded when weapply the A* graph search? Please explainReminder: B is a state, S-C-B and S-A-B are nodes.Please list the nodes in the order they areexpanded and assume that t
