Deterministic and stochastic global optimization techniques for planar covering with ellipses problems

Andretta, M.; Birgin, E.G. - In: European Journal of Operational Research 224 (2013) 1, pp. 23-40

Problems of planar covering with ellipses are tackled in this work. Ellipses can have a fixed angle or each of them can be freely rotated. Deterministic global optimization methods are developed for both cases, while a stochastic version of the method is also proposed for large instances of the...

Deterministic global optimization in ab-initio quantum chemistry

Janes, Pete; Rendell, Alistair - In: Journal of Global Optimization 56 (2013) 2, pp. 537-558

A large number of problems in ab-initio quantum chemistry involve finding the global minimum of the total system energy. These problems are traditionally solved by numerical approaches equivalent to local optimization. While these approaches are relatively efficient, they do not provide...

Mixed integer non-linear programming and Artificial Neural Network based approach to ancillary services dispatch in competitive electricity markets

Canizes, Bruno; Soares, João; Faria, Pedro; Vale, Zita - In: Applied Energy 108 (2013) C, pp. 261-270

Ancillary services represent a good business opportunity that must be considered by market players. This paper presents a new methodology for ancillary services market dispatch. The method considers the bids submitted to the market and includes a market clearing mechanism based on deterministic...

Power-aware scheduling of preemptable jobs on identical parallel processors to meet deadlines

Różycki, R.; Węglarz, J. - In: European Journal of Operational Research 218 (2012) 1, pp. 68-75

This paper deals with a power-aware scheduling of preemptable independent jobs on identical parallel processors where ready time for each job is given and its completion time has to meet a given deadline. Jobs are described by (different) continuous, strictly concave functions relating their...

Gradient Estimation using Lagrange Interpolation Polynomials

Brekelmans, Ruud; Den Hertog, Dick; Hamers, H.J.M.; … - Tilburg University, Center for Economic Research - 2003

In this paper we use Lagrange interpolation polynomials to obtain good gradient estimations.This is e.g. important for nonlinear programming solvers.As an error criterion we take the mean squared error.This error can be split up into a deterministic and a stochastic error.We analyze these errors...
