x) (4 points) If k is a positive integer, a k-coloring of a graph G is an assignment of one of k possible colors to each of the vertices/edges of G so that adjacent vertices/edges have different colors. Draw pictures of each of the following (a) A 4-coloring of the edges of the Petersen graph. (b) A 3-coloring of the vertices of the Petersen graph. (e) A 2-coloring (d) A...
Show the operation of depth-first search (DFS) on the graph of Figure 1 starting from vertex q. Always process vertices in alphabetical order. Show the discovery and finish times for each vertex, and the classification of each edge. (b) A depth-first forest classifies the edges of a graph into tree, back, forward, and cross edges. A breadth-first search (BFS) tree can also be used to classify the edges reachable from the source of the search into the same four categories....
Draw the DFS search tree with starting vertex E and break ties alphabetically. Assuming unit edge length (i.e., ignore edge weight), draw the BFS search tree with starting vertex E and break ties alphabetically. Suppose the Dijkstras algorithm is run on the graph with starting vertex E: (i) draw a table showing the intermediate distance values of all vertices at each iteration of the algorithm; (ii) show the final shortest-path tree.

Show all the vertices as they are discovered in sequence starting from 1 to the last vertex included in T. b.[3] Find a Breadth-First Search tree T for the above graph starting with the vertex 0.

The Knapsack Problem in Python Not using the exhaustive search method or the Dynamic Programming Method, find another method that accomplishes the task of the knapsack problem in python. PLEASE DON'T USE THE EXHAUSTIVE SEARCH METHOD OR THE DYNAMIC PROGRAMMING METHOD, I DON'T NEED THOSE. THANK YOU.
For the following graph: BFS
(a) Perform BFS on the following graph starting at vertex m show
v.d and v.π for each vertex.
(b) Draw the Breadth first predecessor tree resulting from
running the algorithm in part (a).
Using the following graph and Dijkstra's algorithm, calculate the shortest distance to each other vertex starting from vertex A. Label all vertices with the total distance (from A). Indicate the order nodes are added to cloud. Draw a Minimum Spanning Tree for the graph. You should label all nodes in the tree, but you do not need to indicate edge weights or total distance. 2 D C L 7 6 2 7 2 A K B 4 7 4 1...
A 2-coloring of an undirected graph with n vertices and m edges is the assignment of one of two colors (say, red or green) to each vertex of the graph, so that no two adjacent nodes have the same color. So, if there is an edge (u,v) in the graph, either node u is red and v is green or vice versa. Give an O(n + m) time algorithm (pseudocode!) to 2-colour a graph or determine that no such coloring...
