精彩書摘

　　A linear optimization problem is the minimization of a linear function over a polyhedral set which can be viewed as the intersection of an affine space and the coneof nonnegative orthant. Many problems can be formulated as, or approximated bya linear optimization problem. There are many versions of interior-point methodsfor linear optimization. But the basic scheme of these methods is to remove theconstraint set and add a multiple of the barrier function to the objective function.Therefore, the barrier-based scheme reduces the constrained problem into a seriesof unconstrained problems, then to "trace" the path formed by the optimal solutions of unconstrained problems. "Trace" means that the optimal solutions ofunconstrained problems can be replaced by a good enough approximation of theoptimal solutions of unconstrained problems. The procedure of the scheme canbe gone on with updating the barrier parameter until the optimal set of linearoptimization problem is reached.

前言/序言

　　錐優化問題是一個凸規劃問題，它的目標函數是綫性函數，約束集是仿射空間和一個錐的交集，它從優化問題可行域的結構推廣瞭綫性規劃問題，為求解非綫性最優化問題提供瞭一種新的框架，錐優化有凸結構和豐富的對偶理論，對偶問題具有對稱的簡潔結構，同時，又有廣泛應用背景，除瞭在傳統學科，在經濟、金融、管理和工程技術等領域亦有廣泛的應用，近年來，錐優化與新興學科有瞭廣泛交叉和應用，如在無綫傳感網絡、信息理論、編碼理論等信息學科找到瞭豐富的應用，20世紀80年代齣現的內點算法推動瞭算法計算復雜性研究的發展，也成為求解錐優化問題的強大工具，迄今為止，錐優化和內點算法已成為數學規劃和優化領域最活躍的研究課題之一。
　　本書根據作者和其閤作者Roos教授、Ghami博士、王國強博士近年來的研究工作，全麵介紹求解綫性規劃、P（K）綫性互補問題、半正定優化、二階錐優化基於核函數的內點算法，核函數的重要性體現在它有簡單的解析錶達式、容易計算的高階導數等良好性質。
