ere is a proposed algorithm to solve the single source shortest paths problem in a weighted directed graph G with possibly negative edges weights, but no negative weight cycles:Form the graph G' from G by adding the same positive number, p, to all of the edge weights in the graph. This positive number should be chosen so that all the edge weights in G' are positive. (p = 1 + | min edge weight in G|). Run Dijkstra's algorithm on G'.
Is it true that the parent array produced by Dijkstra's algorithm on G' will also give the shortest paths in the original graph, G? Justify your answer with a counterexample or a sketch of a correctness proof.
How does he calculate the signature on each of m1j mod n (for positive integer j), m1-1 mod n, m1*m2 mod n, and in general m1j*m2k mod n (for arbitrary integers j and k)?
