Sommario/riassunto |
|
Almost every month, a new optimization algorithm is proposed, often accompanied by the claim that it is superior to all those that came before it. However, this claim is generally based on the algorithm's performance on a specific set of test cases, which are not necessarily representative of the types of problems the algorithm will face in real life. This book presents the theoretical analysis and practical methods (along with source codes) necessary to estimate the difficulty of problems in a test set, as well as to build bespoke test sets consisting of problems with varied difficulties. The book formally establishes a typology of optimization problems, from which a reliable test set can be deduced. At the same time, it highlights how classic test sets are skewed in favor of different classes of problems, and how, as a result, optimizers that have performed well on test problems may perform poorly in real life scenarios. |

|
Autour des questions de conservation, de valorisation et de réactivation, qu’il s’agisse de bibliothèques ou de collections d’instruments, les contributions rassemblées dans ce recueil s’attachent à des lieux spécifiques et les ancrent dans des histoires d’hommes et de femmes qui, depuis leur création jusqu’à aujourd’hui, les ont fait vivre et revivre. Les lecteurs et les lectrices pourront ainsi participer à la grande aventure historique des savoirs scientifiques, en partant d’ |

objets matériels qui leur sont inéluctablement liés. Le Congrès national des sociétés historiques et scientifiques rassemble chaque année universitaires, membres de sociétés savantes et jeunes chercheurs. Ce recueil est issu de travaux présentés lors du 145e Congrès sur le thème « Collecter, collectionner, conserver ». |
