We review classical valid linear inequalities for mixed-integer programming, i.e., Gomory's fractional and mixed-integer cuts, and discuss their use in branch-and-cut. In particular, a generalization of the recent mixed-integer rounding inequality and a sufficient condition for the global validity of classical cuts after branching has occurred are derived.
