Oh yes that's correct, I must have meant this part: https://github.com/argmin-rs/argmin/blob/e9bebb21d99d2ccad1c36d7373e7f4f53eec1539/crates/argmin-math/src/nalgebra_m/dot.rs#L23-L39

Hi @jonboh, I am very sorry for the very very late reply. I have been rather busy over the last couple of months and currently only have limited access to...

Hi @jonboh , thanks again for the amazing work! :) > I've trasformed the existing examples into benchmarks. I've kept the original examples, as benchmarks should be more stable than...

I investigated this and I was able to reproduce the problem with L-BFGS, MoreThuenteLineSearch and the multidimensional Rosenbrock function. First I thought the problem was a untrustworthy gradient, and to...

I must apologize, I did not read your first post carefully enough and did not notice that you had already changed the bounds. :man_facepalming: I though you had changed the...

> What I also find very interesting about the configuration parameters, is that with the following min/max very close to each other, the first iteration is much closer to a...

With #416, the error is now handled slightly better. L-BFGS terminates with `SolverExit(reason)` where `reason` is the textual representation of the line search error. This isn't great, because you'll want...

There is [`BrentRoot`](https://docs.rs/argmin/latest/argmin/solver/brent/struct.BrentRoot.html), which, as far as I remember, is similar to `brentq` in scipy. ~~Maybe @Armavica, who implemented `BrentRoot` in #77 can comment.~~ Edit: My bad, `BrentRoot` was actually...
