Recoverable Robustness by Column Generation [PDF]
, 2011 Real-life planning problems are often complicated by the occurrence of disturbances, which imply that the original plan cannot be followed anymore and some recovery action must be taken to cope with the disturbance. In such a situation it is worthwhile to arm yourself against common disturbances. Well-known approaches to create plans that take possible,

On Link Scheduling Under Blockage and Interference in 60-GHz Ad Hoc Networks
IEEE Access, 2015 In this paper, we tackle the problem of minimum time length link scheduling in 60-GHz ad hoc wireless networks using directional antennas with directional beamforming, under both traffic demand and signal to interference and noise ratio constraints. Both

Robust Optimization for the Two-Dimensional Strip-Packing Problem with Variable-Sized Bins
Mathematics, 2023 The two-dimensional strip-packing problem (2D-SPP) emerges as a notable variant of the cutting and packing (C&P) problem, aiming to optimize the arrangement of small rectangular items within unique strips with a fixed width and infinite height to ...

Aperture Shape Generation Based on Gradient Descent With Momentum
IEEE Access, 2019 Direct aperture optimization (DAO) is an effective method to generate high-quality intensity-modulated radiation therapy treatment plans. In generic DAO, the direction of negative gradient descent is generally used to determine the aperture shape ...

The Angular Set Covering Problem
IEEE AccessWe present an innovative extension of the Set Covering Problem, transitioning from a traditional radial covering to an angular covering structure. The decisions are based on locating the facilities and identifying the directional servers installed in ...

One-parametric analysis of column-oriented linear programs
Operations Research Perspectives, 2023 A linear optimization problem which is amenable to column generation and contains a single parameter in the objective function is considered. We extend and adapt the standard linear programming column generation scheme to effectively and efficiently ...
