This collection of papers covers a wide spectrum of computational optimization topics, representing a blend of familiar nonlinear programming topics and such novel paradigms as semidefinite programming and complementarity-constrained nonlinear programs. An informal categorization of the papers includes algorithmic advances for special classes of constrained optimization problems, analysis of linear and nonlinear programs, algorithmic advances, B-stationary points of mathematical programs with equilibrium constraints, applications of optimization, some mathematical topics and systems of nonlinear equations.
