Prоblem 1: Applicаtiоn оf Mаximum Flow (6 points) A project mаnager needs to assign four critical development Projects ({cal P} = {P_1, P_2, P_3, P_4}) to three specialized Consultants ({cal C} = {C_A, C_B, C_C}). The technical compatibility between projects and consultants is known: (P_1) can be handled by (C_A) or (C_B). (P_2) can be handled by (C_A) or (C_C). (P_3) can be handled only by (C_B). (P_4) can be handled by (C_A) or (C_C). Each project must be assigned to exactly one consultant. The primary constraint is that each consultant can handle a maximum of two projects. Formulate a maximum-flow problem that determines whether it is possible to assign all four projects to the consultants, respecting both the compatibility and the consultant capacity constraints. Give a clear description of the flow network: a directed graph (G), a source (s), a sink (t), and a capacity function (c). Problem 2: Edmonds-Karp Algorithm (4 points) Consider the flow network (G) shown below. Your task is to perform the first iteration of the Edmonds-Karp algorithm.Draw the complete residual graph (G_{f_1}) that results after this first flow augmentation. Your graph should clearly label all nodes and the residual capacity of all remaining forward and new backward edges. Note: If multiple shortest paths of the same length exist, please choose the one that is lexicographically first, e.g., (s to a to dots) before (s to b to dots).
