[Dip] Branch and Price

[arocco at ing.uchile.cl]

Hello, my name is Adolfo from Chile, I am working on my thesis to  
solve a crew scheduling for a pharmacy, the problem is complicated in  
the sense ti has a lot of constraints and variables, I have been  
implementing a column generation in gams but each column has about 380  
nodes (CP approach would not be good), so I do not know what would be  
a good approach to solve a branch and price, a friend of mine  
suggested me to email you because maybe the DIP (I do not know it)  
might be helpful.

Regards Adolfo.
