Consider eight points on the Cartesian two-dimensional x-y plane. a g C For each pair of vertices u and v, the weight of edge uv is the Euclidean (Pythagorean) distance between those two points. For example, dist(a, h) : V4? + 1? = /17 and dist(a, b) = v2? + 0² = 2. Because many pairs of points have identical distances (e.g. dist(h, c) V5), the above diagram has more than one minimum-weight spanning tree. dist(h, b) = dist(h, f) Determine the total number of minimum-weight spanning trees that exist in the above diagram. Clearly justify your answer.
I am eager to learn. Please explain too. For each graph representation, what is the appropriate worst-case time complexity for printing the vertex label of all the neighbors of a given vertex. Assume that vertex label retrieval from a typical integer vertex representation is O(1). The choices are: O(V+E), O(E), O(V), or O(1). Adjancy Matrix = ____ Edge List = ____ Adjacency List = ____
Correct answer will upvoted else downvoted. You are given a coordinated chart G which can contain circles (edges from a vertex to itself). Multi-edges are missing in G which implies that for every single arranged pair (u,v) exists all things considered one edge from u to v. Vertices are numbered from 1 to n. A way from u to v is a grouping of edges to such an extent that: vertex u is the beginning of the principal edge in the way; vertex v is the finish of the last edge in the way; for all sets of neighboring edges next edge begins at the vertex that the past edge finishes on. We will expect that the unfilled succession of edges is a way from one u to another. For every vertex v output one of four qualities: 0, in case there are no ways from 1 to v; 1, in case there is just a single way from 1 to v; 2, in case there is more than one way from 1 to v and the number of ways is limited; −1, if the number of ways from 1 to v is endless.

Consider a graph with five nodes labeled A, B, C, D, and E. Let's say we have the following edges with their weights: A to B with weight 3 A to C with weight 1 B to C with weight 3 B to D with weight 1 C to E with weight 4 D to E with weight 2 a. Find the shortest path from A to E using Dijkstra's algorithm (Would anything change if B to C weight was changed from 3 to 4? To 1? What about 5?)

Assume that we are given an undirected graph G=(V,E). Consider that Dijkstra's algorithm found a shortest path in G, called SP, between two nodes A and X of V. Is it true or false that if we reverse the nodes on SP, we get a shortest path from X to A? Prove or disprove.

Correct answer will be upvoted else downvoted. Computer science. Consider an undirected weighted diagram 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: Assuming 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. Assuming i+1=j, there is an edge of weight p among I and j. Here gcd(x,y,… ) signifies the best normal divisor (GCD) of integers x, y, .... Note that there could be numerous edges among I and j if both of the above conditions are valid, and assuming both the conditions come up short for I and j, there is no edge between these vertices. The objective is to find the heaviness of the base traversing tree of this chart. Input The principal line contains a solitary integer t (1≤t≤104) — the number of experiments. The primary line of each experiment contains two integers n (2≤n≤2⋅105) and p (1≤p≤109) — the number…
Attached is the pseudocode for Boruvka's algorithm. What is a counterexample that shows this algorithm does not work? Draw out the graph of this counterexample and explain why the algorithm would be unable to compute an MST with your example.
An undirected graph G = (V,E) is said to be k-colorable if all the vertices of G can be colored using k different colors such that no two adjacent vertices have the same color. Design an algorithm that runs in time O(n + e) to color a graph with two colors or determine that the graph is not 2-colorable.
