Abstract Objective Because it is impossible to know which statistical learning algorithm performs best on a prediction task, it is common to use stacking methods to ensemble individual learners into a more powerful single learner.Stacking algorithms are usually based on linear models, which may run into problems, especially when predictions are hig

We consider the problem of constructing generic supporting hyperplanes to be used within a (branch and) bound-and-cut algorithm.We review some of the properties that these hyperplanes should enjoy.It is generally Brushes admitted that they should cut a parasitic point generated during the process.We argue that the advantages of restricting supports
