Program bacuy_eq: Computing Phase Diagram of Ba-Cu-Y
====================================================

The archive contains my code that I have depeloped during my work on
[1] in 1995.

The goal is to compute an equilibrium composition in the Ba-Cu-Y
system by usingnonlinear programming (DONLP2). File readme.txt is the
manual.

Requirements:

1) Fortran IMSL routine ZX3LP for linear programming.  
2) DONLP2 (Do Nonlinear Programming): http://plato.la.asu.edu/donlp2.html.

The situation with DONLP is much more difficult. My code does not work
with the current version. In the directory donlp2/ you will find
donlp.h that describes my interface. What I did at that time is the
coversion of the DONLP Fortran code to C by f2c and then some hacking.
Note that it allows, in principle, to make memory management.

The code have been written under under Borland C++ 4.0 and now I have
fixed it to compile under gcc 3.3. It happened not to be too
difficult. The most problem was to convert the string class that I
used at that time (NCS String Library by Namir Clement Shammas) to
string from the Standard Library.

Files:

readme.txt is a manual; 

bacuy.h is a header; 

bacuy_eq.cpp is a driver;

bacuy_td.cpp contains the Gibbs energies as well as the transformation
subroutines described in the paper; 

bacuy_lp.cpp contains calls to
linear programming (ZX3LP); 

bacuy_dp.cpp contains routines for DONLP;

paper.bat is a script with which I have made plotting for the paper.
