A presentation of general results for discussing local optimality and computation of the expansion of value function and approximate solution of optimization problems, followed by their application to various fields, from physics to economics. The book is thus an opportunity for popularizing these techniques among researchers involved in other sciences, including users of optimization in a wide sense, in mechanics, physics, statistics, finance and economics. Of use to research professionals, including graduate students at an advanced level.

Ce livre est exclusivement consacre aux algorithmes numeriques d'optimisation (quasi-Newton, faisceaux, programmation quadratique successive, points interieurs); les bases theoriques (conditions d'optimalite, multiplicateurs de Lagrange) sont supposees connues.
Son but est de familiariser le lecteur avec ces algorithmes, qui sont pour la plupart bien classiques. Leur description insiste sur leur implementation numerique, ils peuvent etre programmes directement par un lecteur experimente. Le cote theorique n'est pas pour autant neglige, avec demonstration de chaque theoreme de convergence ou vitesse de convergence; souvent, ces demonstrations utilisent des hypotheses minimales.
