Breadth-first search starts at a given vertex h, which is at level 0. In the first stage, we go toall the vertices that are at the distance of one edge away. When we go there, we markedas "visited," the vertices adjacent to the start vertex s - these vertices are placed into level 1.In the second stage, we go to all the new vertices we can reach at the distance of two edgesaway from the source vertex h. These new vertices, which are adjacent to level 1 vertex and notpreviously assigned to a level, are placed into level 2. The BFS traversal ends when each vertexhas been finished.The BFS(G, a) algorithm creates a breadth-first search tree with the source vertex, s, as its root.The predecessor or parent of any other vertex in the tree is the vertex from which it was firstdeveloped. For every vertex, v, the parent of v is marked in the variable π[v]. Another variable,d[v], calculated by BFS has the number of tree edges on the way from s tov. The breadth-firstsearch needs a FIFO queue, Q, to store red vertices.Algorithm: Breadth-First Search TraversalBFS(V, E, a)1.2. do color[u] ← BLACK3. d[u] ← infinity4. π[u] ← NIL5. color[s] ← RED ?

Simplifying Assumptions of wire frame representation Neglect colour - consider Intensity: For now we shall forget about colour and restrict our discussion just to the intensi
Write an algorithm for multiplication of two sparse matrices using Linked Lists.
What is Assertions Introduction At every point in a program, there are generally constraints on the computational state that should hold for program to be correct. For ins
In this unit, the following four advanced data structures have been practically emphasized. These may be considered as alternative to a height balanced tree, i.e., AVL tree.
(1) (i) Add the special form let to the metacircular interpreter Hint: remember let is just syntactic sugar for a lambda expression and so a rewrite to the lambda form is all t
Suppose there are exactly five packet switches (Figure 4) between a sending host and a receiving host connected by a virtual circuit line (shown as dotted line in figure 4). The tr
In a doubly linked list, also called as 2 way list, each node is divided into 3 parts. The first part is called previous pointer field. It contains the address of the preceding
Various graph traversal schemes Graph Traversal Scheme. In many problems we wish to investigate all the vertices in a graph in some systematic order. In graph we often do no
Suppose that there is a Beta(2,2) prior distribution on the probability theta that a coin will yield a "head" when spun in a specified manner. The coin is independently spun 10 tim
