The number of nodes expanded during the A* search is? (Enter - 1 if the search took too long) Consider the 8-sliding tile puzzle with the initial state:23145786and the usual goal state:1 2 345678What is the number of expanded nodes/paths during a A* search, breadth-first graph search, anddepth-first graph search when using the code in search.py?Hint: astar_search(problem, h=None, display=False) (https://github.com/aimacode/aima-python/blob/master/search.py#L415) already has a "display" parameter that can be set to True toprint the number of expanded nodes at the end.eight_puzzle = EightPuzzle(??)print(astar_search(eight_puzzle, h=None, display=True).solution())For breadth-first search(https://github.com/aimacode/aima-python/blob/master/search.py#L238)and depth-first search(https://github.com/aimacode/aima-python/blob/master/search.py#L216),you will have to add a similar "display" parameter to those functions to print the number of expandednodes.

In this assignment, you will design the AddNode and AddEdge methods for the supplied graph data structure. The AddNode and AddEdge methods are to support the construction of undirected (bi-directional) graphs. That is if node A is connected to node B then node B is also connected to node A. In addition to the AddNode and AddEdge methods, create a method called BreadthFirstSearch that accepts a starting node and performs a Breadth First Search of the graph. The algorithm for the breadth first traversal is provided below 1. Add a node to the queue (starting node) 2. While the queue is not empty, dequeue a node 3. Add all unvisited nodes of the dequeued node from step 2 and add them to queue 4. End While Demonstrate your methods by creating the graph depicted in Figure 1 below and running the Breadth First Search on the graph using 0 as the starting node. (see image below) You may use C++, C#, to implement this program as long as the following requirements are met. A C++, or C#…
Take a look at the graphs in A Short Tour of Bad Graphs by C. J Schwarz of Simon Fraser University. Once you have reviewed these graphs, write a brief response, organized by the following points Graphs Link: https://alg.manifoldapp.org/api/proxy/ingestion_sources/339ee58b-7d40-4bc2-aa1d-0061aa89bf09 Which graph was the most misleading? Be sure to reference the section that contains the graph (for example, graph 4.6). Do you think this graphical error was intentional? What reasons do you think contributed to this misleading statistic? Would another method be more suitable to represent this data? How would you represent this data accurately?
