P.4 (The Shortest Path Problem) A mail service company operates on network of postal hubs, represented in the figure below. We assume that hubs identified by nodes and that fixed delivery costs are associated with links between select hubs. These fixed costs are p once the company decides to move one mail order issued by a customer on a given link. Assume a customer issues a deliv order from Hub #1 to Hub #7. Notice that the mail company always tries to answer orders at the lowest total delivery co a) Formulate this problem as a linear (possibly binary) programming problem. b) Solve the problem using Excel Solver. c) Use Dijkstra's algorithm to solve the problem. Show clearly all the steps of the algorithm in action.

QUADRATIC PRIMES This question is adopted from Project Euler Question 27. (https://projecteuler.net/problem=27) The quadratic formula n^2 + n + 41 will produce 40 primes for consecutive integer values 0 <= n <= 39. However, when n = 40, this formula will not generate a prime number. Another interesting quadratic formula n^2 – 79n + 1601 produces 80 prime numbers for consecutive values 0 <= n <= 79. The Question: find a and b such that when -999 <= a <= 999 and -1000 <= b <= 1000, the quadratic form ?^2 + ? × ? + ? produces the maximum number of primes for consecutive values of n, starting with n = 0. Requirement: MUST BE WRITTEN IN C++ - Print the 40 primes generated by formula n 2 + n + 41 - Print the 80 primes generated by formula n 2 – 79n + 1601 - Write a function that takes in an integer and returns whether the given number is prime or not. - Output the value of a, b and how many consecutive values of n (count the starting zero!) can be generated. - Submit…
