Hi Dieter,
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

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

version. I remember that you had provided a new release for this

Ok, but then how do I get a glp_arc from a SWIGTYPE_p_glp_arc and

doubleArray_getitem() or intArray_getitem()? In the MinimumCostFlow.java
example, there is no glp_graph or glp_arc object.
Thanks,

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
