Enactment 1: Optimisation
Due date: 30 Aug 19 12:00
Where to submit: Submit the enactment rumor via the Blackboard turnitin
enactment patience order.
This enactment is desert 20% of the aggregate marks control the way.
Control this enactment, you are required to propel extinguished the mode of attempting to work-out
different optimisation totals. Control each interrogation, you are required to rumor your
results in component. It should grasp your best disentanglement and its similar disentanglement
procedures. If you are asked to work-out those sub-questions using MATLAB, then their
MATLAB spring decree is required.
Marks gain be awarded based on how polite your patience addresses the above
points.
Interrogation 1
You possess undeniable types of chicken wire to set-up a transient ring control holding
chicken at your backyard. You drawing to set-up a triangular ring (the lengths of
three sides are x, y and z, respectively. See Figure 1)
Figure 1 Triangular ring (chicken progeny)
You possess 100m of Type-1 chicken wire, and you deficiency to maximise the area of the
ring control your ardent materials.
– If z=18, content meet the lengths of couple sides x, y using the Lagrange
multiplier order. (Note: you are asked to observe a couple-dimensional
(2D) optimisation act.)
x

(15 marks)
– If the lengths of couple sides possess the forthcoming relationship: x=y. Content meet the
lengths of three sides x, y, z using the Successive Parabolic Interpolation
order and Newton’s order. Content apply it to be a one-dimensional
optimisation total and collect your matlab decree.
