Question

Consider the following graph. We need to search the following state space to find a goal. There are three goals (nodes 7, 14, and 24). When we find a goal, we stop searching. When we have multiple nodes to visit, the priority is given to the node whose node number is less than the others. (1) We are going to search the nodes in the above tree by applying Breadth-first search. Write the order of nodes that are generated to find a goal. (2) We are going to search the nodes in the above tree by applying Breadth-first search. Write the order of nodes that are evaluated (checked) to find a goal. (3) We are going to visit the nodes in the above tree by applying Depth-first search. Write the order of nodes that are generated to check a goal. (4) We are going to visit the nodes in the above tree by applying Depth-first search. Write the order of nodes that are evaluated (checked) to check a goal. (5) We are going to visit the nodes in the above tree by applying Depth-first search with depth limit 3. Write the order of nodes that are generated to check a goal. (6) We are going to visit the nodes in the above tree by applying Depth-first search with depth limit 3. Write the order of nodes that are evaluated (checked) to check a goal. (7) We are going to visit the nodes in the above tree by applying Depth-first iterative deepening search. Write the order of nodes that are evaluated to check a goal.

Explanation / Answer

Solution:

Breadth-first search uses queue data structure while searching for goal,

1)

The order is

Goal found at node 7.

2)

Evaluated nodes are:

3)

Depth-first search uses Stack data structure,

Generated nodes are:

4)

Evaluated nodes are:
