[Help-glpk] Question about Lagrange multiplier
Hi All, I would like to build a library of the constrained maximization based on Lagrange multiplier and using this multiplier a minimize library. (I have to use Lagrange because the second library use the result of the first.) I do not need the extremum only the Lagrange multiplier on the extremum. I looked the manual of the glpk but I could not find the solutin for t he above mentined issue. My question is are there any possibilities to get the Lagrange multiplier using glpk? If yes the second part of the question: how to . Any help appreciate.

[Help-glpk] incorrect version number in glpk.h
In glpk 4.24 the header glpk.h was not changed properly in order to reflect the new minor version number. To fix the bug please replace line 33 in file glpk.h: #define GLP_MINOR_VERSION 23 by the following one: #define GLP_MINOR_VERSION 24 This should be done before compiling and installing the package. ___ Help-glpk mailing list Help-glpk@gnu.org http://lists.gnu.org/mailman/listinfo/help-glpk
Re: [Help-glpk] GLPK-JNI
I downloaded the Java-GLPK-Interface (GLPK 4.8) and was looking for JAVA implementations of a WLP (Warehouse Location Problem) in its many variations that is compatible with this interface. I would also be thankful if anyone can send larger WLP (many restrictions and variables) in Mathprog and Java. Please see http://lists.gnu.org/archive/html/help-glpk/2007-11/msg00036.html . This is a MathProg implementation. ___ Help-glpk mailing list Help-glpk@gnu.org http://lists.gnu.org/mailman/listinfo/help-glpk
