本書幾乎囊括了所有主流的凸優化算法。包括梯度法、次梯度法、多面體逼近法、鄰近法和內點法等。這些方法通常依賴于代價函數和約束條件的凸性(而不一定依賴于其可微性)，并與對偶性有著直接或間接的聯系。作者針對具體問題的特定結構，給出了大量的例題，來充分展示算法的應用。各章的內容如下： 第1章，凸優化模型概述； 第2章，優化算法概述； 第3章，次梯度算法； 第4章，多面體逼近算法； 第5章，鄰近算法； 第6章，其他算法問題。本書的一個特色是在強調問題之間的對偶性的同時，也十分重視建立在共軛概念上的算法之間的對偶性，這常常能為選擇合適的算法實現方式提供新的靈感和計算上的便利。
隨著大規模資源分配、信號處理、機器學習等應用領域的快速發展，凸優化近來正引起人們日益濃厚的興趣。本書力圖給大家較為通俗地介紹求解大規模凸優化問題的算法。本書幾乎囊括了所有主流的凸優化算法。包括梯度法，次梯度法，多面體逼近法，鄰近法和內點法等。這些方法通常依賴于代價函數和約束條件的凸性(而不一定依賴于其可微性)，并與對偶性有著直接或間接的聯系。作者針對具體問題的特定結構，給出了大量的例題，來充分展示算法的應用。

很好的書，喜歡，要好好讀了。
印刷精美，包裝的很結實，物流也很給力，好評。
不錯的一本書，就包裝能不給力
東西很不錯
買來當參考書的，這么厚的英文書讀完還是要很久的。。。
