Yes, given the current implementation in BCP, you will typically want to
generate your vars in compute_lower_bound - then, perhaps, pass it to
generate_vars_in_lp. There is some discussion on this topic here:

> I suppose I should generate my variables in the "generate_vars_in_lp" method. However, before doing that, the method "compute_lower_bound" is called. My question is: should I generate my variables in "compute_lower_bound" to know if I can update the true lower bound, or I lost some detail?
