I'm not sure why these aren't being flagged on CRAN yet, but when run with `r-devel` with address-sanitization flags on I get lots of errors ... haven't yet tried to see if this is new in `r-devel` ..…

If I run a BOBYQA instance from within a BOBYQA cost function, the call-back pointer, which in turn calls a lambda expression with captured references to variables, seems to be overwriting the memory …

Although nlminb is currently being used, adding the bobyqa optimizer may provide an alternative routine to consider in the event of model convergence problems. Is the bobyqa optimization routine some…

On Julia `v1.10.0` and PRIMA `v0.2.0`, I get
```
using PRIMA
cost_func(x) = sum(abs2, x)
bobyqa(cost_func, randn(4))

Hello.
Please see [issue #794](https://github.com/lme4/lme4/issues/794) for the [lme4](https://cran.r-project.org/web/packages/lme4/index.html) package for R, where as part of debugging, it seems t…

bobyqa gives different solutions when given the same initial values, bobyqa algorithm is deterministic, so It should give same solutions if given same initial values

Dear Prima,
A great thanks for developing so powerfull optimisation.

See the discussion in https://github.com/lme4/lme4/issues/744 regarding `PRIMA.bobyqa` in linear mixed models. It may be even more useful to switch to `PRIMA.bobyqa` for GLMM optimization because tha…
