B1- Perform A* search on the following state space graph, starting at A and reaching G. Draw the search tree with the values of each node. What is the path to goal?
Which of the statements are correct? (Select all that applies.) Group of answer choices A digraph is a graph whose edges are all directed. Digraphs can be applicable for detecting wash trade in financial market. Dijkstra's algorithm is based on the greedy method. Kruskal algorithm can be used to create a Minimum Spanning Tree. BFS runs in O(V+E) , where V is the number of vertices and E is the number of edges in the graph. DFS runs in O(V+E) as well.

(Graph Theory) In chess, a knight can move from a square to another square if one of their coordinates differs by 1, and the other differs by 2. A knight's tour is a traversal by knight moves starting at a square, visiting each square once, and returning to the start. Does a 7 × 7 chessboard admit a knight's tour? If so, show the tour.
Graph ColoringNote that χ(G) denotes the chromatic number of graph G, Kndenotes a complete graph on n vertices, and Km,n denotes the complete bipartite graph inwhich the sets that bipartition the vertices have cardinalities m and n, respectively. (c) Compute χ(K3,3). Justify your answer with complete details and complete sentences. (d) For n, m ∈ N, compute χ(Km,n). Do not justify your work. (e) Give an example of a graph G whose chromatic number is 3, but that contains no K3 as a subgraph
Given below are two statements: S1: If a Graph G is n colorable then it's also n+1 colorable. S2: Every Bipartite graph is 2 colorable Which of the above statement(s) is/are correct?
