My student claimed that the three fundamental page replacement algorithms (FIFO, LRU, and optimal) are identical in their abstract design, with the exception of the characteristic that is used to choose the page to be replaced. I was of the opposite opinion. (a) What is the property of the FIFO algorithm that you are referring to? (b) What is the name of the algorithm that you are referring to? What is the LRU algorithm and how does it work? What is the pptimal algorithm in its most basic form? The general algorithm for these page replacement strategies should be included in the specification (b).

Application of data structures to fast image recognition (very simplified) • The setting is that some image processing device gives you a 5 × 6 matrix M of bits. • We categorise these images into YES and NO answers, and this categorisation is fixed. The questions are: 1. What is the fastest data structure from the module to compute from the matrix the YES/NO answers? And how much time does an answer take? 2. How can the matrix be transformed into a standard input for the data structure? And what is the size of the data structure?
What does heuristic search mean exactly? What distinguishes this algorithm from others, and what are its pros and disadvantages?
As compared to alternative data structures like a linked list or an array, the advantages of a binary search tree become immediately obvious. So, to clarify, what are assemblers? To whom or what does one refer when seeking information on a compiler? Just who is responsible for the translations?
Suppose you are using a search algorithm to solve the 15-puzzle problem (i.e., the 4x4 version of the sliding-block puzzle we discussed in class). What are the benefits and drawbacks of using a depth first search? What are the benefits and drawbacks of using a breadth first search?
Please provide answers to the following questions based on the previous code(JAVASCRIPT): What are the weaknesses or limitations of the current implementation? Does the current implementation utilize the Monte Carlo Tree Search (MCTS) algorithm? If not, please describe the algorithm used for the implementation. What are the expectations or objectives of the current implementation in terms of performance and functionality?
In the context of computer science, what does the word "linker" really refer to?
Select the correct answer for the question below: Dynamic programming is an algorithm pattern ... 1.Is not applicable to algorithms which use recursion. 2.That is applicable to almost every set of circumstances and can be widely implemented. 3.That is applicable to only a narrow range of circumstances. 4.Offers poor efficiency gains, when applicable.
Give four page replacement algorithms a name and a description. Compare and contrast them?
Assume we are given the task to build a system that can distinguish junk e-mail. What is in a junk e-mail that lets us know that it is junk? How can the computer detect junk through a syntactic analysis? What would you like the computer to do if it detects a junk e-mail-delete it automatically, move it to a different file, or just highlight it on the screen?
We believe that Flynn's taxonomy may benefit from having an extra layer added to it. In that case, what precisely is it about today's computers that makes them so much more advanced than their predecessors?
We saw the mechanics of Tree Traversals and discussed how they're different from one another, but if we want to write practical software, we also need to know when we should be using the techniques we're learning about. In each of the scenarios described below in which a tree traversal is required, what would be the appropriate kind of tree traversal to use? For each one, briefly explain (in no more than a sentence or two) why. 1. You're writing an analysis tool for a hierarchical organization, in which there is one person fundamentally in charge, to whom some number of people report, to each of whom some number of people report, and so on. There is a ranking in the organization, so the person in charge has rank 1, the people who report to that person have the rank 2, the people who report to the rank-2 people have the rank 3, and so on. Your input is this kind of organizational hierarchy. Your desired output is to be able to find the highest-ranking person (i.e., the person with the…
How was telephone interface technology designed in early 1900's to suit the process being undertaken using the technology available at the time? Was there any evidence that an attempt was made to understand how human cognition and behaviour might influence the design of that technology?
