5.03-1. Dijkstra's Algorithm (3, part 1). Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E (note: the start node here is E) to all other nodes using Dijkstra's algorithm. Using the algorithm statement used in the textbook and its visual representation, complete the "Step 0" row in the table below showing the link state algorithm’s execution by matching the table entries (i), (ii), (iii), and (iv) with their values.
4. In Optimal page algorithm, the page that will be used later is swapped-out over a page that is to be used immediately. 5. Under which of the following scenarios is page replacement algorithm required? 6. Which page replacement algorithm is associated with each page, the time when the page was brought into memory?
Consider the following page reference string: 7, 2, 3, 1, 2, 5, 3, 4, 6, 7, 7, 1, 0, 5, 4, 6, 2, 3, 0, 1. Assuming pure demand paging with three frames (3 pages can be in memory at a time). a)Using FIFO replacement algorithm, show the content of the memory (which pages are in memory) for each page reference. b) How many page faults resulted from this algorithm? c) Repeat a) and b)above with LRU algorithm.
The objective is to simulate virtual memory paging and evaluate the performance of different page replacement algorithms using reference strings. Simulate virtual memory paging for a specific reference string and analyzing the performance of various page replacement algorithms. The goal is to compare the page fault rates generated by different algorithms, including Belady's Optimal algorithm. Task 1: Page Replacement Algorithms Implement the following page replacement algorithms: FIFO (First-In-First-Out): Implement the FIFO page replacement algorithm. LRU (Least Recently Used): Implement the LRU page replacement algorithm. Random: Implement a random page replacement algorithm. This means that you will replace a random page. Belady's Optimal: Implement Belady's Optimal page replacement algorithm. This requires you to look ahead in the reference string and find which of the pages that you have currently in frames will go the longest without reference. Task 2: Simulation Simulate…

Suppose that the data mining task is to cluster points (with (x,y) representing location coordinates) into three clusters, where the points are A1(2,10), A2(8,4), A3(7,5), A4(1,2), A5 (2,5), A6(5,8), A7(6,4), A8(4,9). The distance function is Euclidean distance and k-means (with k=3) for clustering. Suppose initially we assign A1, A4, and A6 as the centroid for the three clusters. Show the three cluster centroids as well as a set of points in each cluster after each round until convergence.
Successive elements are inserted into a dynamically expandable field. After j insertions becomes, if j is a power of two (ie for j = 1, 2, 4, 8, 16 etc.), a restructuring carried out, in which new memory is requested and the field is copied if necessary, what a causes a maximum time requirement of j. Find the average cost of an insertion after inserting n elements . Amortization costs cj are to be introduced for this purpose. Which account balances (or potentials) emerge from the analysis? This is a practice task wich could be relevant for my exam. How do i solve this? Cant find anything for Amortization costs in my skript.
Correct answer will be upvoted else downvoted. Computer science. You are given a cluster a comprising of n integers. At first all components of an are either 0 or 1. You wanted to deal with q inquiries of two sorts: 1 x : Assign to cut out the worth 1−ax. 2 k : Print the k-th biggest worth of the cluster. As an update, k-th biggest worth of the cluster b is characterized as following: Sort the cluster in the non-expanding request, return k-th component from it. For instance, the second biggest component in exhibit [0,1,0,1] is 1, as in the wake of arranging in non-expanding request it becomes [1,1,0,0], and the second component in this cluster is equivalent to 1. Input The principal line contains two integers n and q (1≤n,q≤105) — the length of the given cluster and the number of questions. The subsequent line contains n integers a1,a2,a3,… ,an (0≤ai≤1) — components of the underlying cluster. Every one of the accompanying q lines contains two integers. The…

In our practise task there is a taks regarding the "Amortization method of cost analysis". I tried to do it bu couldnt really find anything in the script that would me hlep solve it. "Successive elements are inserted into a dynamically expandable field. After j insertions becomes, if j is a power of two (ie for j = 1; 2; 4; 8; 16 etc.), a restructuring carried out, in which new memory is requested and the field is copied if necessary, what a causes a maximum time requirement of j. Find the average cost of an insertion after inserting n elements . Amortization costs ^cj are to be introduced for this purpose. Which account balances (or potentials) emerge from the analysis?" How do i do this?
