Blackbox optimization deals with situations in which the objective function and constraints are typically computed by launching a time-consuming computer ...
référence BibTeXA Variance-Based Method to Rank Input Variables of the Mesh Adaptive Direct Search Algorithm
The Mesh Adaptive Direct Search algorithm (MADS) algorithm is designed for nonsmooth blackbox optimization problems in which the evaluation of the funct...

The Mesh Adaptive Direct Search (MADS) class of algorithms is designed for nonsmooth optimization, where the objective function and constraints are typical...
référence BibTeXThe Small Octagons of Maximal Width
The paper answers an open problem introduced by Bezdek and Fodor in 2000. The width of any unit-diameter octagon is shown to be less than or equal to `(\fra...

This paper presents a framework to determine optimal maintenance planning of a fleet of complex and independent systems. They are made up of several major co...
référence BibTeXOptimization of Algorithms with OPAL
OPAL is a general-purpose system for modeling and solving algorithm optimization problems. OPAL takes an algorithm as input, and as output it suggests para...
