A possible solution would be for `SolverBenchmark.performance_profiles()` to take two `Dict`s of kwargs instead of one set of `kwargs`: one that will be passed to `BenchmarkProfiles.performance_profiles()` and one that will...
Solution 1 would be great, but not obvious to implement. I have prototype code but it doesn't quite work. Solution 3 would be "easy" to implement and may be the...
@farhadrclass Already implemented the exact solve of $$(B + \sigma I) x = b$$ for LBFGS. It can be implemented for other limited-memory quasi-Newton operators but I believe we need...
@nimgould In this pull request, I build GALAHAD with sanitizers enabled. They are alternatives to Valgrind to diagnose various types of issues. We see issues on both Linux and macOS....
I validated locally that this works. I'll add a small unit test to demonstrate.
@Qfl3x Any progress on this?
Since it’s likely to be indefinite, it will be of very limited use (if any). The forward operator is useful in trust-region methods. The inverse operator would be useful in...
From #368: > We should also add something in the tutorial [limited_memory_bfgs_and_sr1](https://jso.dev/tutorials/introduction-to-linear-operators/#limited_memory_bfgs_and_sr1) to say that since SR1 can be undefinite, only the forward operator is implemented.
If a solver tries to solve an unconstrained problem and, in doing so, evaluates the constraints, there is a serious issue with that solver. We should not encourage that kind...
Yes I think `objcons` should also error if the problem is unconstrained.
