Transcribed Image Text:Consider the following Integer Linear Program:
Minimise:
5x₁ + 4x2
Subject to:
X1
X1

(iii)
X2
4x2

+ X2 ≥ 9
X₁, X2 ≥ 0 and integer
Construct the initial tableau for this problem including all decision,
slack and artificial variables. You should assume the M-method will be
used to solve this, so build the tableau with the objective function
coefficients for any artificial variables set to -M.
(ii)
In the optimal solution to the (non-integer) relaxation of this problem,
X₁ and X2 are both basic and the second constraint is a strict inequality.
Using any method you like (including computer software), derive the
transformation matrix for the optimal solution to the relaxation of this
problem, and use it to construct an optimal tableau for the non-integer
LP (you can assume that the solution is feasible, so no columns for the
artificial variables are needed).
From the tableau you derived in (ii) above, use the dual simplex
method to find the optimal solution to the integer LP. You should
examine (at least) two distinct additional constraints on one of the
decision variables to verify that your solution is optimal for the integer
LP
