Hello,

Am trying to run a model with the following logic in C#. 

1) Run the original model  Min C *X, st. AX<=B . Let Z be the objective value of optimal solution.

2)  Now modifying the model and re running . 

3) Modified problem is  Min D*x, st AX <=B and CX<= Z .

What am trying to look for is can I get the value of the Linear expression CX directly from the first model such that I dont have to write much code in for modeling.

While I modify the problem  using  cplex.addLe in C#  can I store the   product C*X and re-use it  . I mean is there any direct way to get  C*X as linear expression ??

Thanks
