- Problem Alice was given a number line containing every positive integer, x, where 1<=x<=n. She was also given m line segments, each having a left endpoint, l (1<=l<=n), a right endpoint, r (1<=r<=n), and an integer weight, w. Her task is to cover all numbers on the given number line using a subset of the line segments, such that the maximum weight among all the line segments in the chosen subset is minimal. In other words, let S=(l1,r1,w1),(l2,r2,w2),....,(lk,rk,wk), represent a set of k line segments chosen by Alice, max(w1,w2,...,wk) should be minimized. All numbers 1,2,....n should be covered by at least one of k the chosen line segments. It is okay for the chosen line segments to overlap. You program should output the minimized maximum weight in the chosen subset that covers all the numbers on the number line, or -1 if it is not possible to cover the number line. Input format The first line of the input contains an integer, n - denoting the range of numbers…Write a program that implements the FIFO and LRU page-replacement algorithms presented in this chapter. First, generate a random page reference string to each algorithm, and record the number of page faults incurred by each algorithm.

- Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. You are given a parallel table of size n×m. This table comprises of images 0 and 1. You can make such activity: select 3 distinct cells that have a place with one 2×2 square and change the images in these cells (change 0 to 1 and 1 to 0). Your assignment is to make all images in the table equivalent to 0. You are permitted to make all things considered 3nm activities. You don't have to limit the number of activities. It tends to be demonstrated that it is consistently conceivable. Input The principal line contains a solitary integer t (1≤t≤5000) — the number of experiments. The following lines contain portrayals of experiments. The principal line of the depiction of each experiment contains two integers n, m (2≤n,m≤100). Every one of the following n lines contains a parallel line of length m, depicting the images of the following column of the table. It is…Suppose you are given a document of four words {w1, w2, w3, w4}, where w1, w2 are topic words; w3 and w4 are background words. Moreover, count(w1) = count(w3) = 4, and count(w2) = count(w4) = 2. Suppose that the background distribution is given below: Word w W1 w2 w3 W4 p(w|0g) 0.1 0.1 0.5 0.3 Suppose that the EM algorithm generates the following values at the current iteration: Word w W1 w2 w3 W4 p(w|0) 0.44 0.22 0.20 0.14 What are the values of p(w 0) at the next iteration?In the state space shown below, write the order in which states are expanded if the initial state is 4 and there are two goal states: 5 and 8. For example, for breadth first search the answer would be: 4 2 7 1 3 6 8 using depth-first search using iterative deepening. 2 1 3 5
- Mini-Case Google’s PageRank: Google’s PageRank is an algorithm that attempts to inform you where people are coming from when they land on your website and which sources are the most frequent. Note that, as its name suggests, a page rank is an index estimated page by page; it’s not an overall website assessment. Think of the Internet as a big network (duh), where the links aren’t all equal. Just as with people, some of your connections are “more important” (in achieving whatever goals) than others. With clickstreams, if you’re getting a lot of web traffic, is it coming from somewhere impressive like Amazon or from Joe’s-Shoes-and-Tshirts.com? The algorithm weights the more important (more connected) links more than the less important (less connected) links. Say you’re trying to determine the rank of your home page. You figure that’s a good start, and customers can navigate more precisely once they’re in your domain. The ranking model begins by checking all the incoming links to the…You are given a 2 by n grid, where the cell on row i column j contains a non-negative number ai,j . You can start at either cell in the lefttmost column, and your goal is to reach either cell in the rightmost column by a sequence of moves. You can move to an adjacent cell (if it exists) in each of the 4 cardinal directions (up,down, left and right). A path achieves a score equal to the sum of values in its cells. Note that a cell which is used twice in a path only counts its value once to the score of that path.Design an algorithm which runs in O(n) time and finds a path of minimum score from the leftmost column to the rightmost column.Write a program in MIPS Write a program that first initialize a 4 by 4 table with random integer values. Then read the diagonal elements and print each of the diagonal cells. Finally display the sum of all diagonal cells.
