Hi all,
I have my source code written in AMPL for Cplex, and I am currently porting
it GLPK.
The models don't work as is, since the original source code has some
AMPL/CPlex specific commands.
Besides, I am more comfortable writing scripts in C++ than with scripting in
AMPL; however, I find that writing models in AMPL is easier.
I have been able to convert most of my models to GLPK my adding rows,
columns and generating the model row by row, column by column.
I also saw in the manual that there is a function to load models and data
files, however, I want to generate data on the fly i.e. I just want to load
a model, and then
generate data segments in the code. The requirement is such because I have a
custom Branch and Price routine, and have two independent models for the
'master'
and the 'slave'.
Example model:
param n;
set N := {1..n};
.
.
.
var x {N} >= 0;
.
.
.
maximize objective: ...
subject to:
.
.
.
What is the preferred way to do this, since I wasn't able to set the values
of the parameters from the C++ code :|
