1. In BFS (or DFS), there is an for-loop that invokes the sub-routine bfs (G, s) (dfs(G,s)) Given an undirected graph of n nodes and m edges. If the sub-routine bfs(G, s) (dfs (G,s)) is called k times from BFS (or DFS), how many breadth-first (depth-first) trees have been con- structed? How many edges are there in this forest of breadth-first (depth-first) trees? 1. In BFS (or DFS), there is an for-loop that invokes the sub-routine bfs (G, s) (dfs(G,s))...
Q2. Show the execution trace of DFS on the following directed graph. You must show discovery time v.d, finish time v.f, and the v.color for each node as the algorithm progresses. Indicate all tree edges, back edges, forward edges, and cross edges when the final DFS forest is constructed. Assume that the edges going out from a vertex are processed in alphabetical order and that each adjacency list is ordered alphabetically.
3. (8 points-7+1) Figure 4 shows an undirected graph G. Assume that the adjacency list lists the edges in alphabetical order. Figure 3: Graph for P3 (a) Apply depth first search (DFS) to graph G, and show the discovery and finish times of each vertex. In the main-loop of DFS, check the vertices in alphabetical the form dsc/fin, where dsc is the discovery time and fin is the finish time. (b) Draw the DFS tree obtained. 3. (8 points-7+1) Figure...
Implement Depth-First Search (DFS) and Breadth-First Search (BFS) algorithms for a graph in Java.(Can be any graph, just an example of DFS and BFS is sufficient) If it cannot be done for a graph, then just an example of DFS and BFS are enough.
You will be implementing a Breadth-First Search (BFS) and a Depth-First Search (DFS) algorithm on a graph stored as an adjacency list. The AdjacencyList class inherits from the Graph class shown below. class Graph { private: vector _distances; vector _previous; public: Graph() { } virtual int vertices() const = 0; virtual int edges() const = 0; virtual int distance(int) const = 0; virtual void bfs(int) const = 0; virtual void dfs(int) const = 0; virtual void display() const = 0;...

Show how depth-first search works on the graph of Figure 22.6. Assume that the for loop of lines 5–7 of the DFS procedure considers the vertices in reverse alphabetical order, and assume that each adjacency list is ordered alphabetically.

Consider the following directed graph for each of the problems: 1. Perform a breadth-first search on the graph assuming that the vertices and adjacency lists are listed in alphabetical order. Show the breadth-first search tree that is generated. 2. Perform a depth-first search on the graph assuming that the vertices and adjacency lists are listed in alphabetical order. Classify each edge as tree, back or cross edge. Label each vertex with its start and finish time. 3. Remove all the...
