Whats the easiest way to query root relaxation value with JuMP?

I’m reoptimizing and setting “NodeLimit” parameter to 1.

Take a read of [Please read: make it easier to help you](https://discourse.julialang.org/t/psa-make-it-easier-to-help-you/14757).

In particular, it’s easier to help if you provide more information, including what solver you are using, and a snippet of code.

If you are after the root relaxation, you’re probably interested in [https://jump.dev/JuMP.jl/stable/variables/#JuMP.relax\_integrality](https://jump.dev/JuMP.jl/stable/variables/#JuMP.relax_integrality)
