Problem 6Consider a data set that contains 4 Boolean attributes A, B, C,and D, and a Boolean class y. For the Boolean expression below (between the classthe rest of the attributes), it is possible to construct a smaller decision tree that perfectlyclassifies the data without generating the complete tree (i.e., the number of leave nodes isless than 16). Then, draw such a tree.andy = A ^ BA C ^ D

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!)

An independent set in a graph G is a set S of vertices of G (so S is a subset of the vertex set V(G) of G) such that no two vertices from S are adjacent.

Problem: Instance: a caterpillar T Problem: find the number of independent sets in T Design a recursive algorithm based on Divide and Conquer strategy for solving this problem. Prove its correctness. Estimate the time complexity of the algorithm.
for 33 you need to have and understanding what is a graph, and a tree. Have an explanation what is a graph what it is used for, and how it is utilized in general. Same thing with trees. Why are they useful and what are the advantages and disadvantages of these data types. After this please construct a graph (it can be directed or undirected, please make it clear which one you're using) and have a "model" -- drawing of that simple graph, after try to create that in racket.
Given a binary search tree and data of two nodes, find 'LCA' (Lowest Common Ancestor) of the given two nodes in the BST.LCALCA of two nodes A and B is the lowest or deepest node which has both A and B as its descendants. Example:In this example, the green coloured node is the LCA to A and B.Alt TextNote:It is defined that each node is a descendant to itself, so, if there are two nodes X and Y and X has a direct connection from Y, then Y is the lowest common ancestor.Example:Alt TextNote:1. If out of 2 nodes only one node is present, return that node. 2. If both are not present, return -1.3. all the node data will be unique.Input format:The first line of input contains data of the nodes of the tree in level order form. The data of the nodes of the tree is separated by space. If any node does not have left or right child, take -1 in its place. Since -1 is used as an indication whether the left or right nodes exist, therefore, it will not be a part of the data of any node.The following…
= Suppose that we have a B and the size of the search key field V is equal to 10 bytes, the size of the data (record) pointer Pr 6 bytes, and the tree (block) pointer P is 5 bytes and the value of p (the order or the maximum number of a tree pointers in a node) is equal to 20 for an internal node. a) Calculate the block size (B) b) Suppose that we have a B- tree instead of B and based on the block size found in question (a), calculate the order (p) for an internal node in this case.
If a weighted graph is represented by the adjacency list data structure, write a LISP function, neighbors, to return the list ofneighbors of a node.For example,if(setq graph '( (a (b 2) (c 5)) (b (c 3) (d 2)) (c) (d (b 8)) ) ) when call:>(neighbors 'b graph)should return:(c d)
We can think of a tree as being a special kind of directed graph. To model a tree as a graph, we make the nodes of the tree become nodes in the graph and draw an edge from a parent node to each of its children. The drawing on the left shows a tree as a graph; the other three directed graphs do not correspond to a tree. Suppose we want to check if a given directed graph as shown in Figure 3 corresponds to a tree. A tree Not a tree Not a tree Not a tree b. Figure 3: A tree and not a tree structure.
Implement a function to check if a binary tree is balanced. For the purposes of this question, a balanced tree is defined to be a tree such that the heights of the two subtrees of any node never differ by more than one
