PRIMA (https://github.com/libprima/prima)
================================================================================
Basin's Powell-family derivative-free solvers --- COBYLA, NEWUOA, BOBYQA, and
LINCOA (src/solver/{cobyla,newuoa,bobyqa,lincoa}{,.rs}) --- are derived from
PRIMA, Zaikun Zhang's modern-Fortran reference implementation of M. J. D.
Powell's methods. PRIMA is the authoritative source for the exact formulas and
was used as the cross-validation oracle for these solvers. PRIMA is distributed

L-BFGS-B (https://users.iems.northwestern.edu/~nocedal/lbfgsb.html)
================================================================================
Basin's bound-constrained L-BFGS-B solver (the `Lbfgsb` mode of `Lbfgs`) is a
port of the L-BFGS-B version 3.0 Fortran code (April 2011): the generalized
Cauchy point, subspace minimization, compact-form, and `formk` routines
(src/solver/lbfgs/{cauchy,subsm,formk,compact,backend}.rs) are translated from
`lbfgsb.f`. The code is by Ciyou Zhu, Richard H. Byrd, Peihuang Lu, and Jorge
Nocedal (ACM TOMS Algorithm 778), with the version-3.0 subspace-minimization
improvement and correction by José Luis Morales and Jorge Nocedal. It is
released under the New BSD License (a.k.a. Modified BSD / BSD 3-Clause), whose
