Objective Coefficient Rounding and Almost Symmetries in Binary Programs
Dominik Kuzinowicz, Paweł Lichocki, Gioni Mexi +3
This article investigates the interplay of rounding objective coefficients in binary programs and almost symmetries. Empirically, reducing the number of significant bits through ro…
Gridless Parameter Estimation in Partly Calibrated Rectangular Arrays
Tianyi Liu, Sai Pavan Deram, Khaled Ardah +3
Spatial frequency estimation from a mixture of noisy sinusoids finds applications in various fields. While subspace-based methods offer cost-effective super-resolution parameter es…
Constrained C-Test Generation via Mixed-Integer Programming
Ji-Ung Lee, Marc E. Pfetsch, Iryna Gurevych
This work proposes a novel method to generate C-Tests; a deviated form of cloze tests (a gap filling exercise) where only the last part of a word is turned into a gap. In contrast…
The SCIP Optimization Suite 9.0
Suresh Bolusani, Mathieu Besançon, Ksenia Bestuzheva +28
The SCIP Optimization Suite provides a collection of software packages for mathematical optimization, centered around the constraint integer programming (CIP) framework SCIP. This…
Maximum A Posteriori Direction-of-Arrival Estimation via Mixed-Integer Semidefinite Programming
Tianyi Liu, Frederic Matter, Alexander Sorg +3
We propose a joint sparse maximum a posteriori (MAP) estimator for DOA estimation from multiple snapshots, reformulated as a mixed-integer semidefinite program (MISDP). This enable…
