4. This problem is about how we deal with intractable problems. The Traveling Salesperson Problem (TSP)* is a well-known problem that resembles many practical problems in vehicle routing, network design, computer chip layout, and even DNA sequencing. TSP is NP-HARD, meaning that if we can solve TSP in polynomial time, then we can solve any NP problem in polynomial time by converting it into a TSP problem. This quote from Wikipedia sums it up: The most direct solution would be to try all permutations (ordered combinations) and see which one is cheapest (using brute-force search). The running time for this approach lies within a polynomial factor of 0(n!), the factorial of the number of cities, so this solution becomes impractical even for only 20 cities. Select the most accurate statement about TSP: O A greedy algorithm can be used to solve TSP (produce an exact solution) in polynomial time. O A greedy algorithm can be used to approximate a solution to TSP in polynomial time, where the…

Write an efficient algorithm for the following problem, and describe your reasoning. Determine the Time complexity and if you cannot find any polynomial time algorithm, then give a backtracking algorithm. Problem: Tower of Hanoi with Every Tower having some Disks Input: Each of the three towers contains roughly n/3 disks. Tower A contains floor(n/3) largest disks. Tower C contains ceiling(n/3) smallest disks. Tower B contains the remaining disks. The disks at each tower are already sorted according to the typical Tower of Hanoi rule. Output: A set of moves that transfers all the n disks to C maintaining the Tower of Hanoi rule that after each move, the smaller disks at a tower will always be above the larger ones.
