Numerical methods for large-scale nonlinear optimization by N.I.M. Gould, D. Orban and Ph. L. Toint Report TR04/08 16 November 2004 Recent developments in numerical methods for solving large differentiable nonlinear optimization problems are reviewed. State-of-the-art algorithms for solving unconstrained, bound-constrained, linearly-constrained and nonlinearly-constrained problems are discussed. As well as important conceptual advances and theoretical aspects, emphasis is also placed on more practical issues, such as software availability.
