BibTeX reference

This paper addresses the limitations of current satellite payload architectures, which are predominantly hardware-driven and lack the flexibility to adapt to...

BibTeX reference

This paper tackles a complex variant of the unit commitment (UC) problem at Hydro-Quebec, referred to as the transient stability constrained unit commitmen...

BibTeX reference

This paper introduces a new step to the *Direct Search Method* (DSM) to strengthen its convergence analysis.
By design, this so-called *covering step* may e...

RipQP: A multi-precision regularized predictor-corrector method for convex quadratic optimization

We describe the implementation of RipQP, an interior-point algorithm for convex quadratic optimization. Our Julia implementation is open source, and accommo...

BibTeX reference\(\texttt{solar}\): A solar thermal power plant simulator for blackbox optimization benchmarking

This work introduces solar, a collection of ten optimization problem instances for benchmarking blackbox optimization solvers. The instances present differ...

BibTeX reference

The aim of this paper is to analyze the effect of adaptive investments on international environmental agreements (IEAs) focused on reducing greenhouse gas ...

BibTeX referenceOptimal text-based time-series indices

We propose an approach to construct text-based time-series indices in an optimal way -typically, indices that maximize the contemporaneous relation or the pr...

BibTeX referenceBranch-and-Price

Integer (linear) programs are a standard way of formalizing a vast array of optimization problems in industry, services, management, science, and technology....

BibTeX reference

In 1960, Ailsa Land and Alison Doig published the first linear programming-based branch-and-bound algorithm for the solution of mixed integer linear progra...

BibTeX reference

Heterogeneous datasets emerge in various machine learning or optimization applications that feature different data sources, various data types and complex re...

BibTeX referenceA general error analysis for randomized low-rank approximation with application to data assimilation

Randomized algorithms have proven to perform well on a large class of numerical linear algebra problems. Their theoretical analysis is critical to provide gu...

BibTeX referenceStatistical testing of scaling models for precipitation Intensity-Duration-Frequency curves

Producing accurate precipitation Intensity-Duration-Frequency (IDF) curves necessitates robust statistical methodologies. Employing a scaling model to combin...

BibTeX reference

Augmented Lagrangian (AL) methods are a well known class of algorithms for solving constrained optimization problems. They have been extended to the solution...

BibTeX reference

Millions of oil and gas wells are abandoned and orphaned around the world. Due to funding shortfalls, many abandoned and orphaned wells remain unplugged and ...

BibTeX referenceJoint optimization of electric bus scheduling and fast charging infrastructure location planning

Transit authorities are rapidly replacing conventional buses with electric ones because of the increasing concerns about air quality, greenhouse gas emission...

BibTeX reference

The arithmetic-geometric index is a newly proposed degree-based graph invariant in mathematical chemistry. We give a sharp upper bound on the value of this ...

BibTeX referenceRevisiting Boehmer et al. (2021): Recent period, alternative method, different conclusions

We reassess Boehmer et al. (2021, BJZZ)'s seminal work on the predictive power of retail order imbalance (ROI) for future stock returns. First, we replicate ...
