The current released version of JuMP (0.18) does not have the ability to delete variables.

This oversight is fixed in the upcoming release of JuMP. (Read more about that [here](https://discourse.julialang.org/t/mathoptinterface-and-upcoming-breaking-changes-in-jump-0-19/4874).)

If you want to try it out for a spin, there are installation instructions at [JuMP 0.19-beta released (JuMP/MathOptInterface)](https://discourse.julialang.org/t/jump-0-19-beta-released-jump-mathoptinterface/18850). (Warning! It’s a beta!)

Once you’re using the beta, you can read about deleting variables in the [new docs](http://www.juliaopt.org/JuMP.jl/latest/variables/#Deleting-variables-1) .
