Fast algorithms for large scale generalized distance weighted discrimination [PDF]
, 2017 High dimension low sample size statistical analysis is important in a wide range of applications. In such situations, the highly appealing discrimination method, support vector machine, can be improved to alleviate data piling at the margin.

Convex Programs for Temporal Verification of Nonlinear Dynamical Systems [PDF]
, 2007 A methodology for safety verification of continuous and hybrid systems using barrier certificates has been proposed recently. Conditions that must be satisfied by a barrier certificate can be formulated as a convex program, and the feasibility of the ...

A tight MIP formulation of the unit commitment problem with start-up and shut-down constraints
EURO Journal on Computational Optimization, 2017 This paper provides the convex hull description of the single thermal Unit Commitment (UC) problem with the following basic operating constraints: (1) generation limits, (2) start-up and shut-down capabilities, and (3) minimum up and down times.

A Combinatorial Optimization Approach to the Selection of Statistical Units [PDF]
, 2015 In the case of some large statistical surveys, the set of units that will constitute the scope of the survey must be selected. We focus on the real case of a Census of Agriculture, where the units are farms.

Sufficient pruning conditions for MINLP in gas network design
EURO Journal on Computational Optimization, 2017 One-quarter of Europe’s energy demand is provided by natural gas distributed through a vast pipeline network covering the whole of Europe. At a cost of 1 million Euros per kilometer the extension of the European pipeline network is already a multi ...

Bilevel programming for price-based electricity auctions: a revenue-constrained case
EURO Journal on Computational Optimization, 2015 This paper describes the application of bilevel programming to a class of real-life problems in the field of electric power systems. Within the context of electricity markets, market-clearing procedures, i.e., auction models, are used by an independent ...

Pricing American Options by Exercise Rate Optimization [PDF]
, 2019 We present a novel method for the numerical pricing of American options based on Monte Carlo simulation and the optimization of exercise strategies. Previous solutions to this problem either explicitly or implicitly determine so-called optimal exercise ...
