Hello Sylvain,

I have raised the following bug for program Swig used to wrap GLPK:
https://sourceforge.net/p/swig/bugs/1320/

When Swig is fixed I will create a new GLPK for Java release.

Best regards

Hello Sylvain,

the class is now called glp_arc (not _glp_arc) because the definition in 
glpk-4.49/src/glpk.h was changed (relative to glpk-4.47).


See
http://glpk-java.sourceforge.net/apidocs/index.html
for the javadocs.

Best regards

Heinrich,

I am using the glp_graph routines in Java and I just updated GLPK. I was
calling routines such as _glp_arc.getHead().getI() and I'd like to know if
there is some way to use the same kind of routines with the updated

version 4.47.
I look forward to testing the new minimum cost flow algorithm!

Heinrich,

I am using the glp_graph routines in Java and I just updated GLPK. I was
calling routines such as _glp_arc.getHead().getI() and I'd like to know if
there is some way to use the same kind of routines with the updated
version. I remember that you had provided a new release for this feature in
version 4.47.
I look forward to testing the new minimum cost flow algorithm!

AFAIK, there is no such interface yet.

For do that you will need to parse the GMPL model file to build it in the ipopt
internal structure. If you plan to write a parse in C take a look at
glp_read_prob() in the file glpdmx.c of the GLPK source.

Hello everyone!
I am new to GLPK and so far I'm very impressed by it's capabilities. My 
question goes to solving non-linear problems written in  GMPL using e.g. 
ipopt. Is there an interface or could anyone point me into a direction 
where i can learn how to do this? I'm on Linux Mint, so I installed the 
ipopt package available from the repositories...

Thanks,
Dieter
