such an assumption, and only from text such as `A node can be pruned if an upper bound is lower than an existing lower bound' can it be inferred that the algorithm description assumes maximization. Three suggestions: (1) Explicitly state whether the algorithm description assumes minimization or maximization. (2) Make it minimization so that this article is consistent with the `Branch and Bound' article. (3) The information I came here to remember was, during maximization, how the algorithm maintains a lower bound. All that is said here is `integral solutions serve as lower bounds.' Perhaps explain this a little better, for example that an incumbent or `best-so-far' integer solution can serve as a global lower bound, which unlike upper bounds is not node-specific. Thanks!

Hi, I may be missing something, but it seems there is an inconsistency between the `Branch and Bound' article and this `Branch and Cut' article. The `Branch and Bound' article says in the first line of its general description that it assumes minimization. This `Branch and Cut' article never states

Does anyone know of a clear reference as to who first implemented branch and cut? It would be nice to see who had the first paper on this.
