This is great, let's not do a release for it yet though. The structural simplify doesn't work for OptmizationSystem yet in my experience. I will finish up SciML/ModelingToolkit.jl#1983 and #432 soon and then try to write out the tutorial with it working.

Didn't Yingbo fix that up mid December? There's tests on it now.

[Vaibhavdixit02]

You are right, the PR had issues because I had misunderstood the structural simplification for optimization system. I'll create a release and get this out 👍

[ValentinKaisermayer]

What can structual_simplify offer for an optimization problem other than alias elimination?

[ChrisRackauckas]

Tearing. What I wrote out was tearing, which requires splitting and solving subsystems. Alias elimination cannot perform solves.
