A Column Generation Approach Based on Region Growth

open access: yesIEEE Access, 2019
In intensity-modulated radiation therapy (IMRT), a network flow is adopted to solve the pricing problem of the generic column generation approach in order to obtain a deliverable aperture.

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

open access: yesMolecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

On the trade-off between staff-decomposed and activity-decomposed column generation for a staff scheduling problem. [PDF]

open access: yes
In this paper a comparison is made between two decomposition techniques to solve a staff scheduling problem with column generation. In the first approach, decomposition takes place on the staff members, whereas in the second approach decomposition takes ...

Demand-Driven Scheduling of Movies in a Multiplex [PDF]

open access: yes
This paper describes a model that generates weekly movie schedules in a multiplex movie theater. A movie schedule specifies within each day of the week, on which screen(s) different movies will be played, and at which time(s).

Branch-and-price-and-cut for large-scale multicommodity capacitated fixed-charge network design

open access: yesEURO Journal on Computational Optimization, 2014
We present a branch-and-price-and-cut algorithm for solving large-scale instances of the multicommodity capacitated fixed-charge network design problem.

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

open access: yesMolecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

Combinatorial Robust Optimization with Decision-Dependent Information Discovery and Polyhedral Uncertainty

open access: yesOpen Journal of Mathematical Optimization
Given a nominal combinatorial optimization problem, we consider a robust two-stages variant with polyhedral cost uncertainty, called Decision-Dependent Information Discovery (DDID). In the first stage, DDID selects a subset of uncertain cost coefficients

Column Generation

open access: yes
Abstract This chapter describes the classical column generation algorithm used to solve a linear program with a huge number of variables. Besides its main properties, we offer several practical hints to be included in any worthwhile implementation and present a few classical examples of its application.
