Vehicle routing problems concern the linking of a group of customers who must be visited to a set of vehicles and respective drivers, also involving the programming and sequencing of visits. In the method that is based on the concept of gain, the worst possible situation is assumed: the vehicle leaves the DC with the goods destined for a single customer and, after delivery, the vehicle returns to the DC. Then another customer is inserted in this route. This method is known under the name of: ( ) Clark & Wright ( )Insertion of the furthest point ( ) II - OPT ( ) scan ( )III - OPT

Computer science. all dishes are ready in various cafés and consequently Petya needs to get his orders from n better places. To accelerate this interaction, he needs to arrange messenger conveyance at certain eateries. Subsequently, for each dish, there are two choices for Petya how he can get it: the dish will be conveyed by a dispatch from the café I, for this situation the messenger will show up in man-made intelligence minutes, Petya goes to the eatery I all alone and gets the dish, he will spend bi minutes on this. Every café has its own dispatches and they begin conveying the request right now Petya goes out. As such, all dispatches work in equal. Petya should visit all cafés in which he has not picked conveyance, he does this reliably. For instance, assuming Petya needs to arrange n=4 dishes and a=[3,7,4,5], and b=[2,1,2,4], then, at that point, he can arrange conveyance from the…
AT&T is a telecommunications company with a call centre. When customers call the customer service centre, they are queued up to speak with a customer service representative. Customers are asked to wait and are given a specific number if the operators are busy. A customer's wait time could be as little as a minute or as long as 30 minutes. This also varies according to the type of customer. Platinum customers will receive a higher level of priority than Gold customers. Thus, when a call from a Platinum customer is received, it is prioritised for processing. If there are no remaining Platinum customers in the queue, the Gold customer will be served. Demonstrate the scheduling process of a switch in a phone answering system by using queue. Construct a program to demonstrate the problem. Calculate the average waiting time for each call.

Suppose a biking environment consists of n ≥ 3 landmarks,which are linked by bike route in a cyclical manner. That is, thereis a bike route between landmark 1 and 2, between landmark 2 and 3,and so on until we link landmark n back to landmark 1. In the centerof these is a mountain which has a bike route to every single landmark.Besides these, there are no other bike routes in the biking environment.You can think of the landmarks and the single mountain as nodes, andthe bike routes as edges, which altogether form a graph G. A path is asequence of bike routes.What is the number of paths of length 2 in the graph in termsof n?What is the number of cycles of length 3 in the graph in termsof n?What is the number of cycles in the graph in terms of n?
Let A = {a, b, c}, B = {x, y}, and C = {0, 1}. Identify B × B × B.
Consider the following network: a.) Find the shortest path from node 1 to node 8 using Dijkstra’s algorithm. Write the length of the shortest path as well as the edges that compose it. b.) Write an integer programming formulation to find the second-shortest path from 1 to 8 in this network. (Hint: if the shortest path is not available, the second-shortest path becomes the shortest path.)
A certain cat shelter has devised a novel way of making prospective adopters choose their new pet. To remove pet owners’ biases regarding breed, age, or looks, they are led blindfolded into a room containing all the cats up for adoption and must bring home whichever they pick up. Suppose you are trying to adopt two cats, and the shelter contains a total of N cats in one of only two colors: black or orange. is it still possible to pick up two black cats with probability ½, given that there is an even number of orange cats in the room? If so, how many cats should be in the room? How many black, how many orange?
QUESTION 5 The Towers of Hanoi game starts with a pile of disks with different sizes on one of three pegs. The other two pegs start empty. The disks are initially piled in order of size with largest on the bottom. The aim of the game is to transfer all of the disks to a destination peg by moving one disk at a time, never placing a disk on top of a smaller one. The spare peg may be used for intermediate moves. One solution to the problem recursively moves all but the largest disk to the spare peg, moves the largest disk to the destination peg, and then recursively moves all the other disks from the spare peg to the destination peg. This process is described by the following pseudocode: Hanoi( n, start, destination, spare ) // n is the number of disks and start, destination and spare are peg numbers if n>0 Hanoi( n-1, start, spare, destination) moveTopDisk( start, destination) // move top disk on start peg to destination peg Hanoi( n-1, spare, destination, start) Which of the following…
Bus timetables specify to the second the exact arrival and departure time of each bus on each stop. You need to pay for the full fare of every bus you ride and different bus lines charge different fees , but they are flat fees (independent of distance travelled on the line) A travel plan is a sequence of stop-time pairs where stop is a location of a bus stop and time is when we arrive at that stop. The plan is feasible if for any two consecutive pairs (a, t) and (b, t′) in the plan there exists a bus that departs after t and arrives at b at exactly t′. That is, a travel plan does not allow us to walk between stops. Assuming that no two buses arrive at the same time at the same stop, a feasible plan uniquely identifies the bus lines that we need to take to realize the plan. The cost of the plan is the sum of the fares we need to pay. Your task is to design an efficient algorithm that given a departure time t, an arrival time t′, an origin stop a and a destination stop b, finds the…

There are 2016 passengers about to board a plane, numbered 1 through 2016 in that order. Each passenger is assigned to a seat equal to his or her own number. However, the first passenger disregards instructions and instead of sitting in seat number 1, chooses and sits down in a randomly chosen seat. Each subsequent passenger acts according to the following scheme: if their assigned seat is available, they will sit there; otherwise, they will pick at random from the remaining available seats and sit there. What is the probability that the 1512th passenger ends up sitting in their assigned seat? A. 1/2016 B. 1/2 C. 5/8 D. 3/4 E. None of the above
A salesman has a number of cities to visit. They want to calculate the total number of possible paths they could take, visiting each city once before returning home. Return the total number of possible paths a salesman can travel, given n cities. If we have cities A, B and C, possible paths would be: A - B -> C A -> C -> B B -> A -> C B -> C -> A C -> B -> A C -> A > B which gives us 6 as the possible number of paths. Examples paths (4) → 24
