Deep learning has redefined modern standards and performance in several areas such as computer vision and natural language processing. With increasing amou...
BibTeX referenceSemi\(^+\)-supervised learning under sample selection bias
In time-to-event data analysis, the main object of interest is the time elapsed between the occurrence of two ordered events, say \(E_1, E_2\). Sampling fr...
A Simulation model for short and long term humanitarian supply chain operations management
Traditionally, the design of supply chains for humanitarian operations has been developed distinctly for the different disaster management phases, with littl...
BibTeX referenceThe value of randomized strategies in distributionally robust risk averse network interdiction games
Conditional Value at Risk (CVaR) is widely used to account for the preferences of a risk-averse agent in the extreme loss scenarios. To study the effectiven...

In derivative-free and blackbox optimization, the objective function is often evaluated through the execution of a computer program seen as a blackbox. It ...

Very large networks linking dynamical agents are now ubiquitous and the need to analyse, design and control them is evident. The emergence of the graphon the...
BibTeX reference
Graphon-based control has recently been proposed and developed to solve control problems for dynamical systems on networks which are very large or growing w...

In this paper we study the linear quadratic regulation (LQR) problem for dynamical systems coupled over large-scale networks and obtain locally computable l...

Dealing with demand uncertainty in multi-item lot sizing problems poses huge challenges due to the inherent complexity. The resulting stochastic formulation...
BibTeX referenceAdjustable robust optimization reformulations of two-stage worst-case regret minimization problems
This paper explores the idea that two-stage worst-case regret minimization problems with either objective or right-hand side uncertainty can be reformulated ...
BibTeX referenceSpatio-temporal flexibility requirement envelopes for low-carbon power system energy management
The deepening penetration of renewable power generation is challenging how the minute balancing of supply and demand is carried out by power system operators...
BibTeX reference
We consider a class of min-max robust problems in which the functions that need to be robustified can be decomposed as the sum of arbitrary functions. This...
