Inequality Constraints???

Hi,

Firstly, thanks for the great tool! I really appreciate the greatest descent approach which is great for situations where computation times are long and genetic algorithms are not feasible!

My question is: Is there any way to incorporate inequality constraints into Goat?

This would be of great benefit to structural problems where for example we want to minimise steel weights but ensure that stresses and deflection limits are not exceeded.

Thanks,

Sam

Hi Sam,

You may incorporate inequality constraints via "Barrier Functions" into goat. A detailed explanation is beyond the scope of this forum, instead I provide a link to wikipedia: https://en.wikipedia.org/wiki/Barrier_function

If you need further support on this, please send us an email (goat@rechenraum.com) and we'll see how we can help you further.

best, simon
