A Julia interface to the Ipopt nonlinear solver
With this test excluded, Ipopt passes tests on M1. But I don't understand the underlying cause. Closes #315
I have a new toy ```Julia (jump-tests) pkg> test Ipopt Testing Ipopt Status `/private/var/folders/tz/_3rffzvd1hs3rrxssmntjnpw0000gn/T/jl_m7d9vf/Project.toml` [b6b21f68] Ipopt v1.0.2 [b8f27783] MathOptInterface v1.2.0 [9cc047cb] Ipopt_jll v300.1400.400+0 [8dfed614] Test `@stdlib/Test` Status `/private/var/folders/tz/_3rffzvd1hs3rrxssmntjnpw0000gn/T/jl_m7d9vf/Manifest.toml` [6e4b80f9] BenchmarkTools...
I've read issues #278 and #279, which suggest this should have been fixed in [v0.9.0](https://github.com/jump-dev/Ipopt.jl/releases/tag/v0.9.0) but I'm finding in Ipopt.jl v1.0.3 this still not working, unless I'm doing something wrong?...

Replacement for #313, just so I can try it out. I don't know if we should merge this. The alternative is for the user to write a closure, which isn't...
Updated C_wrapper to exposed the variable new_x from Ipopt routines to Julia functions. Maintains backward compatibility for cases where new_x is not used by routines.
I started looking at how we can make in-place resolves of Ipopt fast, but it got tricky because the linear/quadratic components are messy. At some point, we can refactor the...
This snippet consistently segfaults julia: ```julia using GalacticOptim, ForwardDiff, Ipopt rosenbrock(x, p) = (p[1] - x[1])^2 + p[2] * (x[2] - x[1]^2)^2 x0 = zeros(2) _p = [1.0, 100.0] f...
There are a lot of issues relating to linear solvers with Ipopt. #236 was a start at providing some documentation on how to use Ipopt with different solvers: https://github.com/jump-dev/Ipopt.jl#custom-installation. However,...
