A. Given a permutation group acting on coordinates of R n , we consider lattice-free polytopes that are the convex hull of an orbit of one integral vector. The vertices of such polytopes are called core points and they play a key role in a recent approach to exploit symmetry in integer convex optimization problems. Here, naturally the question arises, for(More)
Setting up new immunoassays can be a laborious and expensive task. A relatively new form of multivariate analysis known as neural networks can be applied to this problem with potential savings in reagents and technician time. Neural network software programs for personal computers are now available. We applied one such software package (Brainmaker) to a(More)
