Consider a maximum flow network with an incoming arc-free node other than the source node. Is it possible to remove this node without having any impact on the maximum flow value? Is it also possible to remove a node that isn't the sink node without causing an outgoing arc?

5.04-3. Bellman Ford Algorithm - a change in DV (1, part 3). Consider the network below, and suppose that at t=0, the link between nodes g and h goes down. And so at t=0, nodes g and h recompute their DVs. Following this recomputation, to which nodes will h send its new distance vector? (Note: to answer this question, you'll need to know some of the DV entries at g and h at t=0, but hopefully they'll be obvious by inspection). a 1 1 at t=0 the link (with a cost of 6) between nodes g and h goes down b. compute ∞ g all nodes 8 1 6 1 e 1 compute h 1 1 1 1 node i only nodes i and e only O node h does not send out its distance vector, since none of the least costs have changed to any destination. O nodes i and e and g only node e only

Q1 Consider the following graph representing a network with a, b, c, d, e and z routers andthe metric is the distance. Image attached based on the attached image please show execution of Dijkastra’s algorithm to find the shortest path from router a to all other routers. Thank you in advance!
