Hello! I am very new to Julia and I just downloaded it today!

I’m trying to use JuMPeR for robust optimization cases. But JuMPeR requires Grisu which i understand it no longer used. So I found the work around but it doesn’t seem to be working:

using Pkg
Pkg.add(“JuMPeR”)

Pkg.add(“Grisu”)

if isdefined(Base, :Grisu)
import Base.Grisu
else
import Grisu
end

Glad you’re trying out Julia! Just to be clear, JuMPeR is unmaintained and unsupported. You will undoubtedly have a bad experience getting it to work and dealing with compatibility issues. That said, you can try installing Julia 1.0 with JuMP 0.18.

Ok That works thanks! Would you know if there are any supported and maintained robust optimization Julia libraries? All the ones I find seem to be no longer supported.

I think the best (and most tractable) way to tackle robust optimization problems is to formulate their robust counterpart, and to solve the latter with your favorite appropriate solver. This approach is (as far as I know) the state-of-the-art.
