Tree Traversal:

Tree traversal is a method of visit all the nodes of the tree and also displays their data. All the nodes are connecting via link which means edge. So the edge is used to visit all the nodes in the tree. Tree traversal is classified into three orders. They are:

  • Inorder traversal
  • Preorder traversal
  • Postorder traversal

Inorder traversal - In this method, the left subtree is visited first after that the root node and finally right subtree. In tree traversal every node may represent a subtree itself.

Preorder traversal - In this method, the root is visited first after that the left subtree node and finally right subtree node.

Postorder traversal - In this method, the left subtree node is visited first after that the right subtree node and finally root node is visited.

a) first player is the minimizing player. What move should be chosen?b) What nodes would not need to be examined using the alpha-beta pruning procedure?
Consider the problem of finding a path in the grid shown below from the position S to theposition G. The agent can move on the grid horizontally and vertically, one square at atime (each step has a cost of one). No step may be made into a forbidden crossed area. Inthe case of ties, break it using up, left, right, and down.(a) Draw the search tree in a greedy search. Manhattan distance should be used as theheuristic function. That is, h(n) for any node n is the Manhattan distance from nto G. The Manhattan distance between two points is the distance in the x-directionplus the distance in the y-direction. It corresponds to the distance traveled along citystreets arranged in a grid. For example, the Manhattan distance between G and S is4. What is the path that is found by the greedy search?(b) Draw the search tree in an A∗search. Manhattan distance should be used as the
