Question: Graph G = (V,E) is a directed, edge-weighted graph, and the shortest path between vertices a and b is P. a) Does adding a constant

Graph G = (V,E) is a directed, edge-weighted graph, and the shortest path between vertices a and b is P.

a) Does adding a constant value to every edge-weight change P? Why or why not?

b) Does multiplying every edge-weight by a positive value change P? Why or why not?
