Hi all,
After reading the mailing list for java api, I'm confused.
Is Java api included in the distribution?
According to Yuri
(http://lists.gnu.org/archive/html/help-glpk/2004-01/msg00027.html),
Magic.java is an example. But I didn't see it in my downloaded files
for windows version 4.8 and 4.9
Executables for 32 and 64 bit Windows for GLPK 4.36 have been uploaded to
http://winglpk.sourceforge.net/ http://winglpk.sourceforge.net/ .
In the zip archives you will find the standalone solver GLPSOL and the GLPK
library.
Furthermore the libraries necessary to compile java programs

which java binding to GLPK do you use?
Your coding does not look like using java libraries created
Hello,
I'm looking for a simple code of Java program using Glpk to resolve an MIP
problem.
For example, I consider the following problem:
a integer;
min a+2*b:
s.t. a+b=10
s.t. a=0
s.t. b=0
s.t.
Can anybody write the java code and specify where find the files needed ?
I work on Linux
Hi everybody,
I have been using GLPK (version 4.38) for Java for almost one year now. I
just encontered (for the first time, fortunately) an assert that crashed in
GLPK and that killed my whole Java application. This assert is located
glplib10.c, line 109: xassert(xlcmp(env-t_last, t) = 0
Dear,
I had a problem using GLPK - Java on ubuntu 10:04 - Eclipse
I disabled the prints (enablePrints(false)) and apparently when I need to solve
a linear problem with more than 600 variables it crashes.
when the printing is enabled, the problem does not occur.

Hello again,
I have one more question :(
This time I have a problem with dual
I get dual (all the lines with GLPK.glp_get_col_dual(lp,colId+1)
but just after when it's going to put bounds I got an error

Hello Ricardo,
on a 64bit system you could install two different Java runtimes:
A 32bit runtime and a 64bit runtime.
A 64bit runtime can only load 64bit libraries.
A 32bit runtime can only load 32bit libraries.
Did you check the bitness of the GLPK library (glpk.dylib)?
The glpk_java.dylib
in Java written programs?
I don't know nothing about Java (I seem to recall that the Java interface
is now maintained separately from GLPK), but here
http://qosip.tmit.bme.hu/~retvari/Math-GLPK.html
I downloaded Math-GLPK-Solve-0.05.tar.gz from

Hi all,
I plan to use GLPK by a Java application. I'm happy about the SWIG-based
Java API -
many thanks to Xypron.
My application will use a predefined (MIP) model but dynamically created
data. There are
several possibilities to feed the data to the problem object, so far so
good.

Larry,
Curious. Why is OptimJ released under a commercial license? It is based on
Java, can be use as an Eclipse plug-in, and uses a number of free software or
open source solvers.
Nothing curious: the OptimJ language is based on Java, in the sense
that if you know Java you'll learn
when using this #8216;old #8217;
version.
Hello Marc,
precompiled 32 and 64bit Windows binaries for GLPK are supplied by
project GLPK for Windows at http://winglpk.sourceforge.net. These
include GLPK for Java.
If you want an 32bit IDE for Windows you may look at
