Minimización global de un polinomio en la recta real
Beltrán Royo, César (Institut d'Estadística de Catalunya, 1999)
Article
Accés obertEn este art´ıculo presentamos y probamos num´ericamente un nuevo algoritmo para la minimizaci´on global de un polinomio de grado par. El algoritmo est´a basado en la simple idea de trasladar verticalmente el grafo ... -
Short-term hydrothermal coordination by augmented lagrangean relaxation: a new multiplier updating
Beltrán Royo, César; Heredia, F.-Javier (Francisco Javier) (1999-12)
Article
Accés obertThe Augmented Lagrangean Relaxation (ALR) method is one of the most powerful techniques to solve the Short-Term Hydrothermal Coordination (STHC) problem. A crucial step when using the ALR method is the updating of the ... -
Unit commitment by augmented lagrangian relaxation: testing two decomposition approaches
Beltrán Royo, César; Heredia, F.-Javier (Francisco Javier) (2002-02)
Article
Accés restringit per política de l'editorialOne of the main drawbacks of the augmented Lagrangian relaxation method is that the quadratic term introduced by the augmented Lagrangian is not separable. We compare empirically and theoretically two methods designed ...
