Optimal capacitated ring trees
EURO Journal on Computational Optimization, 2016 We study a new network design model combining ring and tree structures under capacity constraints. The solution topology of this capacitated ring tree problem (CRTP) is based on ring trees which are the union of trees and 1-trees.

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.

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 ...

A robust optimization approach for magnetic spacecraft attitude stabilization [PDF]
, 2016 Attitude stabilization of spacecraft using magnetorquers can be achieved by a proportional–derivative-like control algorithm. The gains of this algorithm are usually determined by using a trial-and-error approach within the large search space of the ...

A Semidefinite Approach for Truncated K-Moment Problems [PDF]
, 2012 A truncated moment sequence (tms) of degree d is a vector indexed by monomials whose degree is at most d. Let K be a semialgebraic set.The truncated K-moment problem (TKMP) is: when does a tms y admit a positive Borel measure supported?

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 ...

Joint dynamic probabilistic constraints with projected linear decision rules [PDF]
, 2016 We consider multistage stochastic linear optimization problems combining joint dynamic probabilistic constraints with hard constraints. We develop a method for projecting decision rules onto hard constraints of wait-and-see type.
