Hello Shaghaeygh, your mail had to be forwarded manually because you are not subscribed to GLPK help list, cf. https://lists.gnu.org/mailman/listinfo/help-glpk
In the GMPL language you can use the table statement to write the results of your models LP1 and LP2 to CSV files or to a SQL database. In LP3 you can read that data. The table statement is described in doc/gmpl.pdf of the source distribution available at ftp://ftp.gnu.org/gnu/glpk/glpk-4.55.tar.gz Examples are available in examples/sql and examples/csv. Please, also have a look at the following pages: https://en.wikibooks.org/wiki/GLPK/ODBC https://en.wikibooks.org/wiki/GLPK/Table_Statement Best regards Heinrich On 05.09.2015 22:27, Andrew Makhorin wrote: > -------- Forwarded Message -------- > From: Shaghayegh Mokarami <[email protected]> > To: [email protected] > Subject: A Request > Date: Sat, 5 Sep 2015 18:55:19 +0430 > > Hi > > I'm not very familar to GLPK. > > > My problem contains two LP model, LP1 and LP2 which be solved > separately. > > The variables of model LP1 and LP2 are defined as x[i,j] and y[i,j], > respectively where > > (i,j) in E, and > > set E within (V cross V); > > set V := 1..n; > > > > I want to use the optimum solutions of LP1 and LP2, in third LP model > LP3 as parameters. > > For example, LP3 contains these commands: > > param x{(i,j) in E}; > > param y{(i,j) in E}; > > > > var z{(i,j) in E}; > > > > > > maximize Val: sum {(i,j) in E} (x(i,j)+ y(i,j))* z(i,j); > > > > How should I save the optimum values of x[i,j] and y[i,j] such that > they can be read in LP3 as parameters. > > > Thank you in advanced > > > Shaghayegh > > > > > > > > > _______________________________________________ > Help-glpk mailing list > [email protected] > https://lists.gnu.org/mailman/listinfo/help-glpk > _______________________________________________ Help-glpk mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-glpk
