Hi,

For my project, im using callbacks to stop optimization, add some variables and constraints and then start optimizing again. After extending variables , if I call model.update() does this remove the previous assignment of values to the old variables? 

Thanks in advance,

Kind regards,

Gert Lek.

  Hi Gert,

  No, the update method does not remove any previous assignments. On your local machine, you usually don't have to call the update method explicitly, because it is called by the optimize method anyway.

  Best regards,
