Multivariate Extrapolation: A Tensor-Based Approach-way data are arranged in the form of tensors, i.e., multi-dimensional arrays. Tensor decompositions are then used to retrieve periodic patterns in the data. Afterwards, these patterns serve as input for time series methods. However, previous approaches to tensor extrapolation are limited to special

Heuristic Search for a Real-World 3D Stock Cutting Problemle cutting standard-sized pieces from sheets or rolls of a given material. We consider an application of this problem arising from the packing industry, where the problem is extended from the standard one or two dimensional definition into the three dimensional problem. The purpose of this work is t

Convex Quadratic Mixed-Integer Problems with Quadratic Constraintsn the duality principle for convex problems to derive suitable lower bounds that can used to select the next node to be solved within the branch-and-bound tree. Numerical results indicate that the new bounds allow the tree search to be evaluated quite efficiently compared to benchmark solvers.
