Longest paths
Can you modify Dijkstra’s algorithm to find the length of the longest path from a vertex s to another vertex t in a directed acyclic graph?
We need at least 10 more requests to produce the answer.

Design an efficient algorithm to find the longest path in a directed acyclic graph. (Must handle general real-valued weights on the edges, including negative values.) Use C, Java, or Python.
5. How would you adapt Dijkstra’s algorithm to solve the single-destination shortest paths problem? In other words, find the shortest path from each node to a single destination node. Consider this question for both (a) undirected and (b) directed graphs.

Dijkstra’s Algorithm: You have to implement the Dijkstra’s
algorithm and apply it on the graph provided below.
You have to take the input from the user as an adjacency matrix
representing the graph, the source, the destination. Then you have
to apply the Dijkstra’s algorithm to find the shortest path from
the source and the destination, and find the shortest
route between the source and the destination.
For the input you have to read it from a file. It will...
graph B
Use the graph B above to trace the execution of Dijkstra’s
algorithm as it solves the shortest path problem starting from
vertex C. Draw the resulting vertex-weighted graph.

Use Dijkstra’s algorithm to find the shortest path from a to z.
In each case make tables similar to Table 10.7.1 to show the action
of the algorithm.

PYTHON ONLY Implement the Dijkstra’s Shortest path algorithm in Python. A graph with 10 nodes (Node 0 to node 9) must be implemented. You are supposed to denote the distance of the edges via an adjacency matrix (You can assume the edge weights are either 0 or a positive value). The adjacency matrix is supposed to be a 2-D array and it is to be inputted to the graph. Remember that the adjacency list denotes the edge values for the...
Consider a directed acyclic graph G = (V, E) without edge lengths and a start vertex s E V. (Recall, the length of a path in an graph without edge lengths is given by the number of edges on that path). Someone claims that the following greedy algorithm will always find longest path in the graph G starting from s. path = [8] Ucurrent = s topologically sort the vertices V of G. forall v EV in topological order do...
