I have the following constraint in my model:

 

Through using the column generation, I'm going to add a new variable to the model. Definitely the coefficient corresponding to the new variable would be:

as the term b_{r 1 m} is also included in the Right-hand side, my question is:
while adding new variable, should I update the Right-hand side as well or not?

  Hi Shahrzad,

  If all variables p(s) on the right-hand side exist from the beginning and are not created via column generation (and only \rho(s,a) are generated), I guess you can define the complete right-hand side in the initial model, right?

  Best regards,
  Mario
