3 emplоyees (E1, E2, E3) must be аssigned tо 3 tаsks (T1, T2, T3), with eаch task assigned tо exactly 1 employee, and each employee assigned to exactly 1 task. The cost of assigning employee “i” to task “j” is (4*i + j), where both the indices “i” and “j” run from 1 to 3. An Integer program has been formulated to determine the cheapest assignment of tasks to employees. The variable x[i][j] takes on the value 1 if employee “i” is assigned to task “j”, otherwise x[i][j] takes on the value 0. Which of these expressions is the correct objective function in sigma notation?
