Hello.
One of the constraints in my model is
lambda<=lambda_-1;<br />I need to solve the model a lot of times in a while loop. Each time lambda_ should be decreased by 1.
How can I do it?
Thank you in advance.

If you use OPL, you can change the data fro script. See example in the OPL documentation, section
ILOG OPL Development Studio  > Language > Language User’s Manual > ILOG Script for OPL

You have several examples of flow control.

Didier.

The script constraint allows a person to write a new constraint, all in Python. A Pyconstraint can have multiple targets (however many the script requires), and even their own options.



[edit] Options

Script
    Sets the Pyconstraint to use.
Target
    Allows you to select what objects the script will target.
Options
    Change some of the constraint's settings.
Refresh
    Forces the scripted constraint to refresh it's settings.
C Space
    The space (Global, Local) which the target is used.
