True or False (If your answer to the question is "False", explain why, and provide correction when possible). (a) Let h(n) be the heuristics for the node n, h(m) be the heuristics for the node m, d(m,n) be the actual minimal cost from node m to n in a graph. A* satisfies the monotone restriction iff d(m,n) <= |h(n)-h(m)|. (b) If an A* heuristics is admissible then it satisfies the monotone restriction. (c) Best-first search guarantees optimality in its returned solution. (d) Least-cost-first search guarantees optimality in its returned solution. (e) If all edges are with unit cost, then Breadth-first search guarantees optimality in its returned solution.

The highway distance between 6 cities named (A ... G) are illustrated in the following adjacency matrix:A B C D E FA 0 7 19   28B 7 0 10 18 40 C 19 10 0 16  17D  18 16 0 14 10E  40  14 0 12F 28  17 10 12 a) Draw the graph that represent such adjacency matrix b) List the right sequence of nodes traversed by the DFS and BFS algorithm starting from node A. c) Does this graph possess a Euler circuit/path? , why? If any of them does not exist, how the graph can be modified to have one? d) Draw the minimum spanning tree of this graph . e) Use the Dijkstra's algorithm to determine the shortest paths from city (A) to all other cities . Determine the shortest path and cost from node A to node E .[Hint: implement the algorithm step by step to show which node will be added in sequence] f) Determine the shortest paths between all pairs of nodes using Floyd-Warshall algorithm.
Can you help me solve this exercise? Please note that the greedy approach described in the advice paragraph does not work.
Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. society can be addressed by an associated, undirected chart of n vertices and m edges. The vertices address individuals, and an edge (i,j) addresses a companionship between individuals I and j. In the public eye, the I-th individual has a pay artificial intelligence. An individual I is desirous of individual j if aj=ai+1. That is if individual j has precisely 1 more unit of pay than individual I. The general public is called entrepreneur if for each pair of companions one is desirous of the other. For certain fellowships, you know which companion is jealous of the other. For the leftover fellowships, you don't have the foggiest idea about the bearing of jealousy. The pay imbalance of society is characterized as max1≤i≤nai−min1≤i≤nai. You just know the fellowships and not the livelihoods. In case it is outlandish for this general public to be industrialist with the given…

You are given a weighted tree T.(As a reminder, a tree T is a graph that is connected and contains no cycle.) Each node of the tree T has a weight, denoted by w(v). You want to select a subset of tree nodes, such that weight of the selected nodes is maximized, and if a node is selected, then none of its neighbors are selected.
Assume you are to write a program to analyze the social connection between students in MTSU. Each student is a node in a undirected graph. An edge is added between two nodes if these two students have close social connections, i.e., in the same club, or in the same department. Which would be a better representation for this graph?

2. A minimum spanning tree (MST) or minimum weight spanning tree is a subset of the edges of a connected, edge-weighted undirected graph that connects all the vertices together, without any cycles and with the minimum possible total edge weight. There are 2 very popular algorthms to calcualte MSTs of a graph. These algorithms are Kruskal's algorithm and Prim's algorithm. Figure 2: A weighted graph and its minimum spanning tree (ii) Can a Minimum Spanning Tree finding algorithm like Prim's algorithms be used to find out the Maximum Spanning Tree? If yes, then explain your steps. If not, explain why not with logic.
