- In a cellular network, each cell has seven channels, two of which are dedicated solely for handoff calls. Assume that both new and handoff call arrivals are subject to a Poisson process. The average arrival rate of new calls and handoff calls is 1.5 and 0.3 calls per minute, respectively. The holding duration of a channel is exponentially distributed, with a mean of 2 minutes. Determine the blocking probability of new and handoff calls.As we all know, heuristic or approximation algorithms may not always provide the best solution to a problem, but they are very efficient in terms of polynomial time. (a) Propose an approximation method for the travelling salesman problem (TSP) and analyze the time complexity and limitations of the proposed approach. (2) Provide two examples of inputs for which the method in (a) produces the best and not-the best answers, respectively. (3) There should be between six and eight nodes in each network.Recall Pigou’s example discussed in class, where there are two roads that connect a source, s, and destination, t. The roads have different travel costs. Fraction x1 of the traffic flow on route 1, and the remainder x2 on route 2. Here consider the following scenario. • The first road has “infinite” capacity but is slow and requires 1 hour travel time, T1 = 1. • The second road always requires at least 15 mins, which then increases as a function of traffic density, T2 = 0.25 + 0.75x2. If drivers act in a “selfish” manner – the user optimal scenario – all the traffic will flow on the second path, as one is never worse off. Worst case scenario for path 2, both paths take one hour. So no one is incentivized to change their behavior. 1. Assume user optimal behavior, and calculate τ the expected travel time per car. 2. If instead we could control the flows, we could minimize the expected travel time. Using the expression in part (a), calculate the optimal allocation of flows x¯1 and ¯x2…
- A group of n tourists must cross a wide and deep river with no bridge in sight. They notice two 13-year-old boys playing in a rowboat by the shore. The boat is so tiny, however, that it can only hold two boys or one tourist. How can the tourists get across the river and leave the boys in joint possession of the boat? How many times need the boat pass from shore to shore?1. Develop a system of linear equations for the network by writing an equation for each router (A, B, C, D, and E). Make sure to write your final answer as Ax=b where A is the 5x5 coefficient matrix, x is the 5x1 vector of unknowns, and b is a 5x1 vector of constants. 2. construct the augmented matrix [A b] and then perform row reduction using the rref() function. Write out your reduced matrix and identify the free and basic variables of the system. 3. Use MATLAB to compute the LU decomposition of A, i.e., find A = LU. For this decomposition, find the transformed set of equations Ly = b, where y = Ux. Solve the system of equations Ly = b for the unknown vector y. 4. Compute the inverse of U using the inv() function. 5. Compute the solution to the original system of equations by transforming y into x, i.e., compute x = inv(U)y 6. Check your answer for x1 using Cramer’s Rule. Use MATLAB to compute the required determinants using the det() function.Major Luna is sending military troops from his base (A) to the town of G. However, there is no direct route between A and G. Instead, the troops must pass through other places, namely: B, C, D, E, and F. The following routes are possible: A to B, A to C, B to F, C to D, C to E, D to G, E to G, and F to G. For some reason, such places can only accommodate a number of soldiers going through these places. B, C, D, E, and F has a capacity of 3, 3, 9, 6, and 4 soldiers. b. Solve the problem using the Ford-Fulkerson algorithm.
- Given arrival and departure times of all trains that reach a railway station. Find the minimum number of platforms required for the railway station so that no train is kept waiting.Consider that all the trains arrive on the same day and leave on the same day. Arrival and departure time can never be the same for a train but we can have arrival time of one train equal to departure time of the other. At any given instance of time, same platform can not be used for both departure of a train and arrival of another train. In such cases, we need different platforms. Example 1: Input: n = 6 arr[] = {0900, 0940, 0950, 1100, 1500, 1800} dep[] = {0910, 1200, 1120, 1130, 1900, 2000} Output: 3.Given arrival and departure times of all trains that reach a railway station.

- Apply the shortest-augmenting path algorithm to find a maximum flow in the following networks.Let G= (V, E) be an arbitrary flow network with source s and sink t, and a positive integer capacity c(u, v) for each edge (u, v)∈E. Let us call a flow even if the flow in each edge is an even number. Suppose all capacities of edges in G are even numbers. Then,G has a maximum flow with an even flow value.Q_ 1 red, 1 blue, 1 black, 1 yellow and 1 white car are all waiting at the traffic lights behind each other.
