- IN PYTHON Given the following six-node wide area network for which the numbers attached to the links are a measure of the “delay” in using that link (e.g., some lines could be more heavily used than others and therefore have a longer wait time), answer the following question. What is the shortest path from node A to node D, where shortest path is defined as the path with the smallest sum of the delays on each individual link? Explain exactly how you went about finding that path.For nodes 0000 and 1111, there exists four node-disjoint paths of length 4 (which happens to be the hamming distance between them). These paths are listed as travel from source 0000 through dimension 0-1-2-3 or 1-2-3-0 or 2-3-0-1 or 3-0-1-2 to the destination 1111. Question 1: how many node-disjoint paths between nodes 0000 and 1010 and what are their length? Question 2: for any two arbitrary nodes with the hamming distance r, how many node-disjoint paths among them with the distance r and what are they?Computer Science Written Q6: What are some practical differences between a consistent and an inadmissible heuristic, in terms of path cost and number of expanded nodes? When and why would you prefer an inadmissible heuristic over a consistent one? When and why would you prefer a consistent heuristic over an inadmissible one?

- Our goal in this problem is to determine the “lowest latency routes” starting from your location. The internet in this problem is modeled by a graph, with vertices corresponding to other clients or servers, and edges representing the links between clients/servers. Each edge is not undirected, i.e., the links are unidirectional. At the same time, each link adds a constant latency if you use the link in your routes. Note that if you need to communicate with your own client, then the latency is 0. We represent your location as the vertex 0. Your goal is to determine the total latency it would take if you used the shortest path route from your location to any other client/server in the network. Input Format Each test case starts with a line containing three integers V, E, and Q, denoting the number of vertices, edges, and queries, respectively. Note that vertices are identified with integers from 0 to V-1. E lines follow, each containing three integers s_i, d_i, l_i, denoting the…Computer Science This problem illustrates some of the difficulties facing network planners when they have to use OADMs that are constrained in what channels they can add and drop. Consider a four-node linear network with nodes A, B, C, and D in that order. We have three wavelengths lambda-1, lambda-2, and lambda-3 available. The OADMs given to us can drop two fixed channels i.e., we can put OADMs that drop either (lambda-1, lambda-2), or (lambda-2, lambda-3), or (lambda-1, lambda-3). Now consider the situation where we need to set up the following light paths – AB, BC, CD, AC, and BD. A) What OADMs would you deploy at each node? B) At a later point, the light path traffic changes and we need to replace light paths AC and BD with AD and BC. What changed would you have to make in order to support the new traffic.What are approaches to Finding the Minimum Path?
