Modern Optimization Modelling Techniques This book contains an expanded version of three series of lectures delivered by the authors at the CRM in July 2009. The theory of optimization understood in a broad sense is the basis of modern applied mathematics covering a large spectrum of topics from theoretical considerations (structure stability) to applied operational research and engineering applications. The compiled material of this book puts on display this versatility by exhibiting the three parallel and complementary components of optimization: theory algorithms and practical problems. The first part is a self contained course on the general moment problem and its relations with semidefinite programming. The second part is dedicated to the problem of determination of Nash equilibria from an algorithmic viewpoint. The last part presents congestion models for traffic networks and develops modern optimization techniques for finding traffic equilibria based on stochastic optimization and game theory. Part I: Moments and Positive Polynomials for Optimization by Jean B. Lasserre Part II: Computation of Generalized Nash Equilibria: Recent Advancements by Francisco Facchinei Part III: Equilibrium and Learning in Traffic Networks by Roberto Cominetti.
