Exercise 4 20= 10+4+6 The rod-cutting problem consists of a rod of n units long that can be cut into integer-length pieces. The sale price of a piece i units long is Pi for i = 1,...,n. We want to apply dynamic programming to find the maximum total sale price of the rod. Let F(k) be the maximum price for a given rod of length k. 1. Give the recurrence on F(k) and its initial condition(s). 2. What are the time and space efficiencies of your algorithm? Now, consider the following instance of the rod-cutting problem: a rod of length n=5, and the following sale prices P1=2, P2=3, P3=7, P4=2 and P5=5.

A ancient magnate is failing. His want is to have solely ONE of his descendant’s receive ALL of his treasure, however which one? He has N quantity of decendants. He works out a answer to locate the one fortunate baby who inherits his wealth. He will get N tokens, label every token with an integer fee and assign every token to a descendant. Each token receives a cost solely once. He locations all the tokens in a circle round him, numbered 1 to N, and begins removing one in K till there is solely one left... Write a software that takes two integer values N and K and prints the token wide variety of the fortunate decendant. Input Format The first line of the entry includes the two integers N and K.

Suppose a salesperson is planning a sales trip that includes n cities. Each city is connected to some of the other cities by a road. To minimize travel time, the salesperson wants to determine the shortest route that starts at the salesperson’s home city, visits each of the cities once, and ends up at the home city. This problem of finding the shortest route is called the Travelling Salesperson Problem (TSP) and is a well-known problem that can be solved using Dynamic Programming. Research about the TSP problem and find an algorithm based on Dynamic Programming for that. Explain the approach, the algorithm, and its time complexity. Use an example to explain the way the algorithm operates
an Office consisting of m cabins enumerated from 1 to m. Each cabin is 1 meter long. Sadly, some cabins are broken and need to be repaired.You have an infinitely long repair tape. You want to cut some pieces from the tape and use them to cover all of the broken cabins. To be precise, a piece of tape of integer length t placed at some positions will cover segments 5,5+1-sit-1.You are allowed to cover non-broken cabins, it is also possible that some pieces of tape will overlap.Time is money, so you want to cut at most k continuouspieces of tape to cover all the broken cabins. What is theminimum total length of these pieces?Input FormatThe first line contains three integers n,m and k(1sns10°, namsloº, Isksn) - the number of broken cabins, the length of the stick and the maximum number of pieces you can useThe second line contains n integers bl,b2,bn (Isbism) - the positions of the broken cabins. These integers are given in increasing order, that is, blOutput Format:Print the minimum total…

I need the algorithm, proof of correctness and runtime analysis for the problem. No code necessary ONLY algorithm. And runtime should be O(n log n) as stated in the question.
Consider the problem of making change for n cents using the fewest number of coins. Assume that we live in a country where coins come in k dierent denominations c1, c2, . . . , ck, such that the coin values are positive integers, k ≥ 1, and c1 = 1, i.e., there are pennies, so there is a solution for every value of n. For example, in case of the US coins, k = 4, c1 = 1, c2 = 5, c3 = 10, c4 = 25, i.e., there are pennies, nickels, dimes, and quarters. To give optimal change in the US for n cents, it is sufficient to pick as many quarters as possible, then as many dimes as possible, then as many nickels as possible, and nally give the rest in pennies. Design a bottom-up (non-recursive) O(nk)-time algorithm that makes change for any set of k different coin denominations. Write down the pseudocode and analyze its running time. Argue why your choice of the array and the order in which you fill in the values is the correct one. Notice how it is a lot easier to analyze the running time of…

method to simulate the growth of an Isolated species from time t = 0 to t = tf ; If the population growth rate (per unit of time) is directly proportional to the additional number of individuals the environment could support. Let the number of individuals at time t be N(t), N(0) = No, and the constant of proportionality - k, 0 < k < 1. Compare the modified Euler approximations with the exact value.
