File with optimization problem
Hi all!
I have calculated a simple optimization problem:
A cylinder should have a volume of 1000cm³.
How big must be height and radius to ensure that the surface is minimal?
In Excel we get after two seconds the (right) solution with radius = 5,42cm and
height = 10,84cm.
But Calc gives me (after more than 15 seconds):
Radius = 3,65cm, height = 23,90cm (see attachment).
The calculation was made with DEPS Evolutionary Algorithm.
What's the problem?
Thanks for your help and best regards
Matthias
