內容提要
全書共分14章,前3章介紹數學模型的問題求解和改進搜尋的基本概念與原理,其餘內容則覆蓋了確定型最佳化領域的幾乎全部內容,除了傳統的線性規劃的模型、算法、對偶理論和靈敏度分析等內容以外,還包括了網路流、整數/組合最佳化、非線性規劃和目標規劃等領域的基本模型和主要算法。此外,本書還包含了遺傳算法、模擬退火、禁忌搜尋和分支切割算法等前沿內容。全書採用統一的理論框架,以簡單的“改進搜尋”思路貫穿始終,全面且循序漸進地演繹了各種最佳化算法和方法,包括傳統的單純形法、牛頓法、網路流算法以及各種啟發式算法,使讀者感受到每次引入的新算法都建立在以往算法的基礎上,直觀且邏輯性強,易於理解。本書收錄了豐富的實際案例,並有大量上機習題,便於理論結合實踐。
作者簡介
ROilaldL,Rardin,美國數學規劃和最佳化理論及其套用運籌學方面的著名學者。於1974年從喬治亞理工學院獲得博士學位,長期任普度大學工業工程系教授、普度大學能源建模研究組(PEMRG)主任和Regenstrief醫療保健工程研究中心(RCHE)主任,還曾擔任美國國家自然科學基金會運籌學和服務企業項目主任。Raldin教授的教學和研究重點是大規模最佳化的建模與算法,包括在醫療保健系統、交通與物流系統以及能源規劃方面的套用。他曾四次榮獲普度大學在工業工程方面的Pritsker傑出教學獎,是美國工業工程學會、運籌學與管理科學學會以及數學規劃學會的會員。Rardin教授現已加入阿肯色大學。
