Hey Nathan,
Tried to run updated code benchmarks but it crashes because **almost** isn't defined/initialized in the
**inverse_newton_sqrt** method.
Also, please include ``require 'benchmark/ips…

I am trying to benchmark solvers on a Diagonal Quasi-Newton Model. I get two issues:
1. I get `type DiagonalQNModel has no field counters`
2. When giving a Quasi-Newton Model to Ipopt, I get `Meth…

I observed some weird behavior in my ODE solve with `NLNewton(; relax = BackTracking())` where the result is obviously wrong. After some digging I wrote a wrapper of `BackTracking` where I reject the …
