Optimizing glass coating lines: MIP model and valid inequalities [PDF]
Glass coating is a specific transformation aiming at improving glass performance. The work presented in this paper deals with the determination of the optimal configuration of the production lines used to perform this operation. We propose a first MIP formulation of the problem and then discuss several types of valid inequalities for improving it.

Valid inequalities for mixed 0–1 programs
A class of valid linear inequalities and facets for the convex hull is derived for a typical region appearing in mixed 0-1 programs. To use these inequalities computationally, it is shown how one can find a most violated inequality by solving a series of parametric equality knapsack problems with multiple choice constraints.

Geometric inequalities for black holes [PDF]
It is well known that the three parameters that characterize the Kerr black hole (mass, angular momentum and horizon area) satisfy several important inequalities. Remarkably, some of these inequalities remain valid also for dynamical black holes.

Concentration inequalities for cross-validation in scattered data approximation [PDF]
Choosing models from a hypothesis space is a frequent task in approximation theory and inverse problems. Cross-validation is a classical tool in the learner's repertoire to compare the goodness of fit for different reconstruction models. Much work has been dedicated to computing this quantity in a fast manner but tackling its theoretical properties ...

Mixed integer programming model with non-circular and guided constraints for architectural layout design optimization [PDF]
Various techniques have been used to solve a challenging architecturallayout design problem for more than a decade, such as an expert system, an evolutionary algorithm, a simulated annealing and a mathematical programming method.

Inequalities for low-energy symmetric nuclear matter [PDF]
Using effective field theory we prove inequalities for the correlations of two-nucleon operators in low-energy symmetric nuclear matter. For physical values of operator coefficients in the effective Lagrangian, the S = 1, I = 0 channel correlations must ...

We present O(n2)an integer linear formulation that uses the so-called “distance variables” to solve the quadratic assignment problem (QAP). The formulation performs particularly well for problems with Manhattan distance matrices.
