In graph theory, graph coloring is a special case of graph labeling; it is an assignment of labels traditionally called "colors" to elements of a graph subject to certain constraints. in its simplest form, it is a way of coloring the vertices of a graph such that no two adjacent vertices share the same color; this is called a vertex coloring.", Wikipedia a) Apply your algorithm in the graph below. What is the accuracy ratio? b) Show that the performance ratio of your algorithm can go unbounded above or never at all.
(a) Let G be a simple undirected graph with 18 vertices and 53 edges such that the degreesof G are only 3 and 7. Suppose there are a vertices of degree 7 and b vertices ofdegree 3. Find a and b. To receive any credit for this problem you must write completesentences, explain all of your work, and not leave out any details. problem 1, continued(b) Recall that a graph G is said to be k-regular if and only if every vertex in G has degreek. Draw all 3-regular simple graphs with 12 edges (mutually non-isomorphic). Hint:there are six of them. To receive credit for this problem, you should explain, as well aspossible, why all of your graphs are mutually non-isomorphic.
Consider eight points on the Cartesian two-dimensional xx-yy plane. For each pair of vertices uu and vv, the weight of edge uvuv is the Euclidean (Pythagorean) distance between those two points. For example, dist(a,h) = \sqrt{4^2 + 1^2} = \sqrt{17}dist(a,h)=42+12=17 and dist(a,b) = \sqrt{2^2 + 0^2} = 2dist(a,b)=22+02=2. Using the algorithm of your choice, determine one possible minimum-weight spanning tree and compute its total distance, rounding your answer to one decimal place. Clearly show your steps.
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?
Wouldyou use the adjacency list structure or the adjacency matrix Strijc each of the following cases? Justify your choice. a. The graph has 10,000 vertices and 20,000 edges, and it is importan as little space as possible. b; The graph has 10,000 vertices and 20,000,000 edges, and it is impo use as little space as possible. c. You need to answer the query arëAdjacent as fast as possible, no how much space you use.
Is the following statement true or false? a. Performing one rotation always preserves the AVL property. b. For any two functions f and g, we always have either f = O(g) or g = O(f). c. We run the breadth-first search algorithm (BFS) on a undirected graph G such that all edges have the same weight. BFS returns the shortest path from a source vertex s to any other vertex.

Correct answer will be upvoted else downvoted. Computer science. You are given an exhibit an of n (n≥2) positive integers and an integer p. Consider an undirected weighted chart of n vertices numbered from 1 to n for which the edges between the vertices I and j (i<j) are included the accompanying way: In the event that gcd(ai,ai+1,ai+2,… ,aj)=min(ai,ai+1,ai+2,… ,aj), there is an edge of weight min(ai,ai+1,ai+2,… ,aj) among I and j. On the off chance that i+1=j, there is an edge of weight p among I and j. Here gcd(x,y,… ) means the best normal divisor (GCD) of integers x, y, .... Note that there could be different edges among I and j if both of the above conditions are valid, and assuming both the conditions fall flat for I and j, there is no edge between these vertices. The objective is to find the heaviness of the base crossing tree of this chart. Input The main line contains a solitary integer t (1≤t≤104) — the number of experiments. The principal line…

For each pair of vertex in no. 3 give the vertex sequence of the longest path connecting them that repeat no edges. Is there a longest path connecting them?
Write a pythone code which triverse the graph (which is available in Attached Image) using Best First Search, Depth First Search and Uniform Cost Search. And find the all the vowels from that graph with their cost separately. Note: For Best First Search and Depth First Search you dont need to consider the path cost.
