Dear help-glpk.
I'm a student learning optimization.
I'm doing optimization modeling in JAVA.
However, there are only 1-dimension variables among the existing
examples
Can you give me an example that has more than 2-dimensional variables?
For example,
If the objective function is sum (s in S, p in P) x (s, p)
Hello Minjun,
sets (like S and P) are not supported by the GLPK library. So you have
to create a column for each combination of s and p in your own Java coding.
If that looks too tedious, the code at
https://www.xypron.de/projects/linopt/
might help you. See the example a

forall (s in S, p in P) x (s, p) is_binary
I want to show it in java.
Could you pass me some more difficult examples than the example in the
existing folder?
Thank you.
Best regards.
