Expert Solution & Answer
Chapter 6, Problem 14E
Explanation of Solution
Reason for TREE-CSP-SOLVER makes arcs consistent starting at the leaves and working backwards towards the root:
- The root is the constraints objects.
- Different attributes of the constraints are assigned to the leaves.
- The
algorithm checks each leaves for arc consistency and forward to its parents upon consistent patterns. - Traversing from leaves to root will give an objective approach to solve the consistency problem...

You are given n chains of lengths l1,l2,… ,ln. You intend to fabricate a tree utilizing some of them.
Every vertex of the tree is either white or dark.
The tree at first just has a white root vertex.
All chains at first comprise just of white vertices.
You can take one of the chains and interface any of its vertices to any white vertex of the tree with an edge. The chain turns out to be important for the tree. The two endpoints of this edge become dark.
Each chain can be utilized close to once.
A few chains can be left unused.
The distance between two vertices of the tree is the number of edges on the most brief way between them.
Assuming there is essentially k white vertices in the subsequent tree, the worth of the tree is the distance between the root and the k-th nearest white vertex.
What's the base worth of the tree you can get? In case it is absolutely impossible to construct…
Draw a KD Tree in the space below with these points inserted in the following order: (7,2), (6,4), (9,6), (8,1), (4,9), and (2,3). Assume the first level of the KD Tree is split along the x-axis. What point (from the KD Tree ) is the nearest neighbor of the point (1,4)?
Given any two distinct vertices of a tree, there exists a unique path from one to the other.
So for that statement, I need to give an informal justification, but I'm not even sure what it means. Can someone explain?

- your task it to find the height of your binary tree. Again,your friends can easily give you the height of your left and right subtrees.
