Weighted Graph:
A graph is termed as weighted graph if each edge of the graph is assigned a weight. The weighted edges stored in the weighted graphs can be stored in adjacency lists.
Weighted edges can be represented using a two-dimensional array. An weighted edge can be represented as “WeightedEdge(u,v,w)”, where “u” and “v” are edges and “w” represents the weight between them.
Example of storing edge in a weighted graph:
Object[][] edges =
{ new Integer(0), new Integer(1), new SomeTypeForWeight(8) };
Dijkstra’s
In computer science, the Dijkstra’s Algorithm is a greedy algorithm that is used compute the minimal distance from a node to all the other nodes in a weighted graph.

- Use a software program or a graphing utility with matrix capabilities to find the eigenvalues of the matrix. (Enter your answers as a comma-separated list.) 1 0 -1 1 1 1 -3 0 3 -3 0 3 3 λ = 0 030arrow_forwardCan you find a more efficient sparse matrix representation (in terms of space and computational overhead)?arrow_forwardThe algorithm for computing the Hamming distance between two sequences of the same length implemented in R, for instance, by first splitting the sequences into vectors with the strsplit function and then using the sum function to count the number of positions at which the two vectors differ.arrow_forward
- Think about the problems with representing weighted graphs using adjacency lists.arrow_forwardImplement a Java example to solve Dijkstra's Shortest Path Algorithm using Adjacency Matrix.arrow_forwardPrim's C++ algorithm. If you provide the software the number of vertices and adjacency matrix of a graph, it will use Prim's method to discover the shortest path across the graph.arrow_forward
- Why Dijkstra's algorithm fails to work on negative weighted graph?arrow_forwardWhen weighted graphs are represented as adjacency lists, what are the limits of this method?arrow_forwardI needed the algorithm for G whose length is even. You can read it in the last line of the question. I don't know where the divisible by 5 part came from. Please solve the question again.arrow_forward

Show your solutions using Python codes. [Side note : I kinda need to compare our code so if you can code it in google collab, that would be nice. ]arrow_forwardUsing map() and reduce(), calculate 1 + 8 + 27 + ... + n 3 in pseudocode. (Use map() and reduce() as pseudo functions. No need to write MapReduce code.)arrow_forward
