Write down the dual of the maximum-flow linear program, as given in lines (29.47)-(29.50) maximize sigma_veV f_sv - sigma_veV f_vs subject to f_uv lessthanorequalto c(u, v) for each u, v elementof V, sigma_v e V f_vu = sigma_v e V f_u v for each u elementof V - {s, t} f_uv greaterthanorequalto 0 for each u, v elementof V. Explain how to interpret this formulation as a minimumcut problem.
