In other words, each edge in the graph must be included in at least one of the chosen paths. arrow_forward Step 2: Transforming Graph A into Graph G To transform A into a graph G suitable for the minimum flow problem, we perform the following steps: Node Splitting: For each node v in A (except s and t), we split v into two nodes vin and vout. Then we add an edge from vin to vout with a lower capacity of 1 and an upper capacity of 1. This enforces that any flow passing through v must be part of exactly one path. Edge Transformation: For each edge (u,v) in A, we create an edge (uout,vin) in G with a lower capacity of 0 and an upper capacity…arrow_forward
