Numerical Optimization presents a comprehensive and up-to-date description of the most effective methods in continuous optimization. It responds to the growing interest in optimization in engineering, science, and business by focusing on the methods that are best suited to practical problems. For this new edition the book has been thoroughly updated throughout. There are new chapters on nonlinear interior methods and derivative-free methods for optimization, both of which are used widely in practice and the focus of much current research. Because of the emphasis on practical methods, as well as the extensive illustrations and exercises, the book is accessible to a wide audience. It can be used as a graduate text in engineering, operations research, mathematics, computer science, and business. It also serves as a handbook for researchers and practitioners in the field. The authors have strived to produce a text that is pleasant to read, informative, and rigorous - one that reveals both the beautiful nature of the discipline and its practical side. There is a selected solutions manual for instructors for the new edition. 数值优化提出了一种全面和不断优化的最有效的方法最新说明。它响应了越来越多的优化工程，科学和商业利益上的最适合实际问题的方法为重点。 这个新版本的书已被彻底更新整个。有新的篇章内部的非线性方法和衍生金融工具免费为优化方法，这两者都是在实践中使用广泛应用 ， 目前许多研究的重点。由于注重实际的方法，以及广泛的插图和练习，这本书可以访问给广大受众。它可以用作工程，运筹学，数学，计算机科学和商业研究生文本。它也可作为研究人员和在外地的手册。提交人一直努力产生一个文本愉快的阅读，信息，严格-一个既显示了该学科及其实际一面美丽的自然环境。 有一个选择的解决方案新版本指导员手册。
