Hippity hoppity, abolish loopity def frog_collision_time(frog1, frog2): A frog hopping along on the infinite two-dimensional lattice grid of integers is represented as a 4- tuple of the form (sx, sy, dx, dy) where (sx, sy) is its starting position at time zero, and (dx, dy) is its constant direction vector for each hop. Time advances in discrete integer steps 0, 1, 2, 3, ... so that each frog makes one hop at every tick of the clock. At time t, the position of that frog is given by the formula (sx+t*dx, sy+t*dy) that can be nimbly evaluated for any t. Given two frogs frog1 and frog2 that are guaranteed to initially stand on different squares, return the time when both frogs hop into the same square. If these two frogs never simultaneously arrive at the same square, return None. This function should not contain any loops whatsoever. The result should be calculated using conditional statements and integer arithmetic. Perhaps the best way to get cracking is to first solve a simpler…
Computer Science Consider a network composed of four web pages. Suppose page 1 has a link to pages 2 and 3. Suppose page 3 has a link to page 4. Suppose page 4 has a link to page 3. 1. Draw a graph to represent this network. Identify any dead-end nodes. 2. Draw a modified graph with artificial edges from dead-end nodes to every node in the graph, as required by the PageRank algorithm. 3. Present the system of PageRank equations for nodes 1 and 2 on the modified graph drawn previously. Let α denote the probability of teleportation.
According to my student, the abstract design of the three basic page replacement algorithms (first-in, first-out (FIFO), and last-in, last-out (LRU), and optimum) is similar, with the only difference being the characteristic that is utilized to determine the page to be replaced. Personally, I thought the exact opposite.(a) When you say that the FIFO algorithm has this quality, what exactly do you mean? What is the name of the algorithm you're referring to in (b)? Just what is the LRU algorithm, and how does it function? In its simplest form, what is the pptimal algorithm?It is recommended that the specification contain the general method for these page replacement schemes (b).
5.03-4. Dijkstra's Algorithm (3, part 4). Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E to all other nodes using Dijkstra's algorithm. Using the algorithm statement used in the textbook and its visual representation, complete the "Step 3" row in the table below showing the link state algorithm’s execution by matching the table entries (i), (ii), (iii), (iv) and (v) with their values.
Consider the (directed) network in the attached document We could represent this network with the following Prolog statements: link(a,b). link(a,c). link(b,c). link(b,d). link(c,d). link(d,e). link(d,f). link(e,f). link(f,g). Now, given this network, we say that there is a "connection" from a node "X" to a node "y" if we can get from "X" to "Y" via a series of links, for example, in this network, there is a connection from "a" to "d", and a connection from "c" to "f", etc.
(3) Using the following graph, draw the Minimum Spanning Tree, and by using Dijkstra’s Algorithm give the shortest path from A to F (do not confuse F with E). You may either draw the shortest path, or write out the steps needed to follow the route you find.
Consider a system with four page frames and a program that uses eight pages. Consider the reference string 0 1 7 2 0 3 1 7 0 1 7 and assume that all four page frames are initially empty. Consider the three following algorithms: a. Optimal page replacement b. FIFO page replacement c. LRU page replacement In each cases show a diagram (ASCII art recommended) that shows which pages are in which frames throughout time, and page faults at the bottom. For instance: would mean that at step 1 page 0 is referenced and loaded into frame 0, which is a page fault; then page 1 is referenced, and so on. The goal is to fill this table to see what in memory when and thus infer the number of page faults. The first 4 steps are ALWAYS the same, as above (i.e., just fill the four frames, with one page fault each time)

My student said that the abstract designs of the three primary page replacement algorithms (FIFO, LRU, and optimum) are similar, with the exception of the characteristic utilized to choose the page to be replaced. I was of the contrary view.(a) Which characteristic of the FIFO algorithm are you referring to? (c) What is the name of the algorithm you're referring to? What is the LRU algorithm and how does it function? What is the pptimal algorithm in its simplest form?The general method for these page replacement schemes must be stated in the specification (b).
3. Assume a graph G = (V, E) represents a computer network where the vertices represent computers and the edges represent point-to-point network connections between the computers. Assume each edge (u, v) of G is associated with a real number f(u,v) between 0 and 1 which represents the probability that the corresponding network connection is faulty. Assume these probabilities are independent. a. Propose an algorithm that finds a path between two given vertices u and v with the smallest probability of being faulty (a path is faulty if at least one of its edges is faulty). b. Analyze the complexity of your algorithm.
