3.A thief robbing a store finds n items. The i" item is worth v; dollars and weighs w; pounds, where v; and wiare integers. The thief wants to take as valuable a load as possible, but he can carry at most W pounds in his knapsack,for some integer W. Which items should he take? This problem is called 0-1 knapsack problem because for each item,the thief either take it or leave behind. No fractional amount from an item can be taken. Consider the most valuable loadthat weighs at most W pounds. If we remove item j from this load, the remaining load must be the most valuable loadweighing at most W-w; that the thief can take from the n - I original items excluding j. Write a simple pseudo code forthe given greedy algorithm description first and show how using this greedy algorithm to solve the problem of Knapsackproblem below. Assume that maximum weight that can be carried is 7 lbs. Does it your code find the optimal solution?Show the optimal solution if it exists.ItemValue ($)Weight (lb)1 2 3 420 310 155 153544

The greedy algorithm for the 0-1 knapsack problem would be to sort the items by their…

A local merchant goes to a market to buy apples with 500 UM. They offer two types of apples: green ones at 0.5 UM per kg and red ones at 0.8 UM per kg. We know that he only has space in his van to transport a maximum of 700 kg of apples and that he plans to sell a kilo of green apples for 0.58 UM and red apples for 0.9 UM. Solve the problem with the graphical method.- How many kilograms of apples of each type should you buy to obtain maximum profit?

The density of an object is 2 g/cm3. To convert this to kg/m3, we need to divide it by 1000 to change grams to kilograms. Then, we need to multiply it by 10 to the power of what number to change cm3 to m3.

Roses 1 2 3 4 5 Profit $5 $15 $24 $30 $35 For each positive integer n, let f(n) be the maximum profit that Flora can make with n roses.For example, if n = 10, Flora can make numerous bouquet combinations, including two 5-rose bouquets (total profit of $70), and a 4-rose bouquet with three 2-rose bouquets (total profit of $75). Provide two different algorithms for calculating f(n): one using Recursion, and one using Dynamic Programming. Explain why both algorithms are guaranteed to return the correct value of f(n).
Four individuals wish to traverse an unstable bridge; they all start on the same side. You have 17 minutes to get everyone to the opposite side. Night has fallen, and they have only one torch. Two individuals may cross the bridge at once at most. Any crossing party, whether one or two individuals, must carry a torch. The torch must be carried back and forth; it cannot, for instance, be hurled. Person 1 crosses the bridge in one minute, person 2 in two minutes, person 3 in five minutes, and person 4 in ten minutes. A dyad must trek together at the slower individual's cadence. Create the algorithm specification that solves the problem.
In the game of 10-pin bowling the bowler has two attempts to knock down pins for every frame of 10-pins, and scores a point for each pin knocked down. If all the pins are knocked down with two attempts, the bowler gets a bonus - whatever score they obtain with their next bowl is doubled. If all the pins are knocked down on the 1st attempt, no 2nd attempt is allowed, and the bowler gets a bonus – whatever score they obtain on their next two bowls are doubled. A student attempts to capture this scoring system in VHDL code, a fragment of which is shown in Figure Q4. Q4 (a) Draw the state transition diagram described by the VHDL of Figure Q4. Discuss whether the VHDL of Figure Q4 correctly scores a game of 10-pin bowling.

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…
There is an upcoming football tournament, and the n participating teams are labelled from 1 to n. Each pair of teams will play against each other exactly once. Thus, a total of matches will be held, and each team will compete in n − 1 of these matches. There are only two possible outcomes of a match: 1. The match ends in a draw, in which case both teams will get 1 point. 2. One team wins the match, in which case the winning team gets 3 points and the losing team gets 0 points. Design an algorithm which runs in O(n2 ) time and provides a list of results in all matches which: (a) ensures that all n teams finish with the same points total, and (b) includes the fewest drawn matches among all lists satisfying (a). Do not write the code, give steps and methods. Explain the steps of algorithm, and the logic behind these steps in plain English.Please give time complexity. list of results mean Any combination of wins, losses and draws.

An evil king has n bottles of wine, and a spy has just poisoned one of them. Unfortunately, they do not know which one it is. The poison is very deadly; just one drop diluted even a billion to one will still kill. Even so, it takes a full month for the poison to take effect. Design a scheme for determining exactly which one of the wine bottles was poisoned in just one month’s time while expending O(log n) taste testers.
