Setting HONOUR_X0 to TRUE in BOBYQA

[vcantarella]

Hi. I am solving a problem in BOBYQA and depending on my x0 choice I get this warning:

Warning: BOBYQA: X0 is revised so that the distance between X0 and the inactive bounds is at least RHOBEG; set HONOUR_X0 to .TRUE. if you prefer to keep X0 unchanged.

Depending on the situation, I would like to fix the x0, but I haven't seen in the documentation any keyword to set this option. Is this implemented somewhere?

Thanks in advance.

Sorry for the late answer. As far as I can see, this option is not available in the C interface to PRIMA which is used by PRIMA.jl but I can see it in the Fortran90 code https://github.com/libprima/prima/blob/bb663c197edc10f7923dda6cb46486998ea08387/fortran/bobyqa/bobyqa.f90#L42.

@zaikunzhang Do you think such option can be part of the C interface?

Thank you for replying @emmt! I think I got the C interface to work with honour_x0. It would be great if someone could take a look: libprima/prima@main...vcantarella:prima:main
