We propose an iterative method named USYMLQR for the solution of symmetric saddle-point systems that exploits the orthogonal tridiagonalization method of Sa...
BibTeX reference
We propose a regularization method for nonlinear least-squares problems with equality constraints. Our approach is modeled after those of Arreckx and Orban ...
BibTeX referenceMonotonic grey box optimization
We are interested in blackbox optimization for which the user is aware of monotonic behaviour of some constraints defining the problem. That is, when incr...
BibTeX reference
We are witnessing an acceleration in the uptake of renewable energy in power systems. Because of the associated variability and uncertainty of renewables, ...
BibTeX reference
Recommender systems make use of different sources of information for providing users with recommendations of items. Such systems are often based on collabor...
BibTeX reference
Given a set of duties to be operated over a cyclic one-week horizon and groups of drivers with similar characteristics, the cyclic bus driver rostering probl...
BibTeX reference
The present work is in a context of derivative-free optimization involving direct search algorithms guided by surrogate models of the original problem. The...
BibTeX reference
We consider a personalized employee scheduling problem with characteristics present in retail stores consisting of multiple departments. In the setting under...
BibTeX reference
In the interest of full disclosure, the reader is advised that I am biased positively towards the book considered here as I have collaborated with its first ...
BibTeX reference
This is a two-part work. In Part I, low-cost and representative reduced-fidelity models of two versions of the HYDROTEL hydrological model are constructed, u...
BibTeX referenceLow-cost and representative surrogate hydrological models. Part I - Construction of surrogates
Dealing with computationally-intensive calibration processes is still common in distributed hydrological modelling despite the computing power growth. Comput...
BibTeX reference
The open-pit mine production scheduling problem aims to optimize the net present value of a mining asset. Several solution methods have been proposed to find...
BibTeX referenceImplementing a smooth exact penalty function for equality-constrained nonlinear optimization
We develop a general equality-constrained nonlinear optimization algorithm based on a smooth penalty function proposed by Fletcher (1970). Although it was ...
BibTeX referenceA game theoretic analysis for community microgrid: Architecture, formulation and optimization
Microgrid, a promising component of smart grid, will potentially yield a free electricity market. This paper proposes a novel construction for a community mi...
BibTeX reference
The airline crew scheduling problem involves determining schedules for airline crew members such that all the scheduled flights over a planning horizon (usua...
BibTeX reference
We consider a class of dynamic collective choice models with social interactions, whereby a large number of non-uniform agents have to individually settle ...
BibTeX referenceDistributed integral column generation
The Integral Simplex Using Decomposition (ISUD) algorithm has been developed recently to solve large set partitioning problems (SPPs) in a primal way, i.e.,...
BibTeX reference
This paper investigates the current patient transportation between services in a large hospital and provides a simulation-optimization solution to reduce com...
