Question 4
Which of the following statements is true?
Statement 1: For every graph G and every maximum flow on G, there always exists an edge such that increasing the capacity on that edge will increase the maximum flow that’s possible in the graph.
Statement 2: Suppose the maximum (s,t)-flow of some graph has value f. Now we increase the capacity of every edge by 1. Then the maximum (s,t)-flow in this modified graph will have value at most f + 1.
Statement 1
Statement 2
Both statements
Neither statement
