This folder contains the source codes related to the article:

Optimization of centroidal Voronoi tessellations.

All codes needed to reproduce the numerical experiments in the paper
are included. They include the necessary codes to run the L-BFGS-B 
method and GEOMPACK.

File 'compile' shows how to compile the code. File 
optvorma-bfgs-test can be used to generate the CVTs diagrams showed
in Section 3.1, file optvorma-bfgsJ2 can be used to reproduce the 
the experiments of Section 3.2, 3.3, 3.4. File evalpoints-bfgs-c 
allows to compute the necessary values to make Figure 8.

L-BFGS-B METHOD
===============
The files blas.f, linpack.f routine.f and timer.f correspond to 
Algorithm 778 L-BFGS-B: Fortran subroutines for large-scale bound-constrained 
optimization. They were taken from

Files: 778.gz778.zip 

GEOMETRY AND GEOMPACK
=====================

The two third party packages GEOMETRY and GEOMPACK correspond to 
files geometry.f90 and geompack2.f90. They were taken from

https://people.sc.fsu.edu/~jburkardt/f_src/geometry/geometry.html

and
