5. Select all true statements about DFS and BFS in the box below. Assume no other algorithms are involved: for example, "DFS can explore a tree" means DFS can achieve it alone without involving with any other algorithms. A. When exploring a wide and shallow tree, DFS is more memory efficient than BFS. B. DFS can find words with increasing order of length in auto-completion. C. BFS can find all the vertices that are reachable from a given vertex, but DFS can not. D. Both DFS and BFS can be used to detect cycles in a graph. E. DFS is generally faster than BFS when exploring a graph.

Recursively, a complete binary tree is a graph. Basis step: One vertex forms a binary tree. Inductive step: If T1 and T2 are disjoint complete binary trees with roots r1, r2, respectively, the graph produced by starting with a root r and adding an edge from r to each of the vertices r1, r2 is also complete. Recursively define a complete binary tree's leaves. Base step: The full binary tree has one root, r. Inductive step: T's leaves are the union of T1's and T2's. Class defines binary tree height h(T). Use structural induction to prove that `(T), the number of leaves of a complete binary tree T, is less than 2 h(T).

Below are the top 3 levels of the game tree (tree of all continuations) of 2x2 go, with symmetry pruning. Each pass move is shown as an empty circle. Draw the next two levels of the game tree (you can prune for symmetry).
Create a recursion tree like for T(n)=3T(n/2)+2n^2, with T(1)=2, for n=8 . Like is done in the figure that calculates the total number of comparisons.
Write programs to do BFS and DFS traverse of the graph, based on the adjacent list structure. By using queue, implement the BFS algorithm and print the node sequence. By using recursive method, implement the DFS algorithm and print the node sequence. The source node of the traverse should be input by the user. BFS: DFS:
Homework: AI Search Techniques Here are a set of slides that illustrate alpha-beta pruning. 1. Annotate the following search tree with the minimax value of each node. MAX MIN MAX 3 6 2 2 1 9 5 3 1 5 4 7 5
4. Consider the graph G, shown below, which is simply a copy of K5. 02 V3 5 V1 24 V5 How many distinct spanning trees does G have? (Hint: Break up your search by the isomorphism type of the tree, as discovered on the previous page. So for example, start by counting the paths of length 5 in G. Then proceed to the next type of tree with 5 vertices. The total number of trees is 125, but please use this answer only to check that your solution is complete!)
