The cutting-planes are generated throughout the branch-and-bound tree. The underlying idea is to work on getting as tight as possible bounds in each node of the tree and thus reducing the number of nodes in the search tree. Of course, there is an obvious trade-off. can you drink alcohol on a ketogenic diet
