%description
Thread-safe C++ trust region optimizers, each exposed both as an R
function and as a C-callable entry point (with function pointers
registered for other packages to call without linking against this
package's shared library) so they can be used from parallel C++ code such
as in 'nlmixr2est'. Includes a port of the two-derivative trust region
algorithm in the 'trust' package by Charles J. Geyer; a port of the
Steihaug truncated conjugate-gradient trust region method from the 'basin'
Rust crate (Steihaug (1983) <doi:10.1137/0720042>); and ports of M. J. D.
Powell's derivative-free BOBYQA (Powell (2009), Report DAMTP 2009/NA06)
and NEWUOA (Powell (2006) <doi:10.1007/0-387-30065-1_16>) Fortran 77 code
<https://github.com/libprima/prima/tree/main/fortran/original>, as
modified and distributed in the 'minqa' package, whose R interface is
reproduced.
