An experimental study of the GAMS/AlphaECP MINLP solver / Toni Lastusilta in Industrial & engineering chemistry research, Vol. 48 N° 15 (Août 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 15 (Août 2009) . - pp. 7337–7345 Titre : An experimental study of the GAMS/AlphaECP MINLP solver Type de document : texte imprimé Auteurs : Toni Lastusilta, Auteur ; Michael R. Bussieck, Auteur ; Tapio Westerlund, Auteur Année de publication : 2009 Article en page(s) : pp. 7337–7345 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Mixed-integer  nonlinear  programming  problems  General  algebraic  modeling  system  GAMS/AlphaECP Résumé : The development of methods to solve mixed-integer nonlinear programming (MINLP) problems has given rise to new solvers and improved the current ones. In this Article, the focus is set on the MINLP solvers in the General Algebraic Modeling System (GAMS) and especially GAMS/AlphaECP. In this Article, a comprehensive comparison of the MINLP solvers is made. In June 2007, GAMS introduced new MINLP solvers: CoinBonmin, AlphaECP, and LINDOGlobal. A description of the improvements made in the second half of 2007 to AlphaECP is given, and the performance of the MINLP solvers in GAMS is examined. Furthermore, the performance of AlphaECP for both MINLP and nonlinear programming (NLP) problems is studied, in conjunction with different subsolvers. Two large collections of problems, MINLPLib and GLOBALLib, are used for all solver performance comparisons.
