Exact separation of forbidden-set cuts associated with redundant parity checks of binary linear codes
Christian Puchert, Andreas M. Tillmann
In recent years, several integer programming (IP) approaches were developed for maximum-likelihood decoding and minimum distance computation for binary linear codes. Two aspects in…

Structured Discrete Shape Approximation: Theoretical Complexity and Practical Algorithm
Andreas M. Tillmann, Leif Kobbelt
We consider the problem of approximating a two-dimensional shape contour (or curve segment) using discrete assembly systems, which allow to build geometric structures based on limi…

Joint Antenna Selection and Phase-Only Beamforming Using Mixed-Integer Nonlinear Programming
Tobias Fischer, Ganapati Hegde, Frederic Matter +3
In this paper, we consider the problem of joint antenna selection and analog beamformer design in downlink single-group multicast networks. Our objective is to reduce the hardware…
