Show how to reduce the following problems to linear programming.
At each vertex, half the flow into the vertex is lost (or kept) at the vertex, and the other half flows out. The goal is to maximize the flow that reaches the destination t.
For each edge e, there is also a fixed cost ce for each unit of flow through the edge. We need to find the maximum flow with the minimum cost. That is, there may be many possible flows that achieve the maximum flow; if there is more than one such flow, find the one of minimum cost. (Hint: you may need to use more than one linear program!)
