This folder contains Fortran 90 implementations of the method (bmregu)
introduced in:

E. G. Birgin and J. M. Martínez, Quadratic regularization with cubic 
descent for unconstrained optimization, submitted.

and the method KSS introduced in:

E. Karas, S. A. Santos, and B. F. Svaiter, Algebraic rules for
quadratic regularization of Newton?s method. Computational
Optimization and Applications 60, pp. 343-376, 2014.

To solve your own problem you must edit the file problem.f90.

To compile bmregu type:

gfortran -O3 bmreguma.f90 bmregu.f90 problem.f90 -o bmreguma -llapack

To compile kss type:

gfortran -O3 kssma.f90 kss.f90 problem.f90 -o kssma -llapack

Both methods can also be used to solve problems from the CUTEst
collection. See the compilation/running scripts included in this
folder.

Relevant files for running bmregu with problems from the CUTEst
collection are: bmreguma-forcutest.f90, cutestwrapper.f90, bmregu.f90,
and the script runbmregu.

Relevant files for running kss with problems from the CUTEst
collection are: kssma-forcutest.f90, cutestwrapper.f90, kss.f90, and
the script runkss.
