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
