A data processing department wishes to assign five programmers to five programming tasks (one programmer to each task). Management has estimated the total number of days each programmer would take if assigned to the different jobs, and these estimates are summarized in the Excel file HW4 under the Assigning Tasks Tab. Hint: Maybe the decisions of allocating programmers to task a binary variable. If a programmer is attached to a task, the corresponding variable is 1 , otherwise, 0 . Make sure you include the constraints to ensure we have one programmer to each task. in Dotermine the assianment that minimizes the total programmer days required to complete all five jobs. 2) How would the solution change if programmer 3 could not be assigned to tasks 2 or 4
