算法設(shè)計與分析
會員

為了便于讀者進行系統(tǒng)學(xué)習(xí)、分類整理知識點及遇到問題時能夠快速找到求解的方法,本書按照算法策略進行劃分,每一章都引入了若干個經(jīng)典問題。通過問題的分析、計算模型的建立、算法的設(shè)計與描述、算法的分析來深入解讀每一種算法策略所能解決的問題范疇及方法。全書共分9章,內(nèi)容包括:算法設(shè)計基礎(chǔ)、算法效率分析基礎(chǔ)、迭代法、蠻力法、分治策略、回溯與分支界限、貪心算法、動態(tài)規(guī)劃、隨機算法。本書非常注重教材的可讀性和實用性,以問題分析→模型設(shè)計→算法設(shè)計描述→算法分析為技術(shù)線路,幫助讀者迅速掌握算法設(shè)計要點,規(guī)范算法設(shè)計、分析及實現(xiàn)的方法。書中例題的問題分析和模型設(shè)計模塊用于培養(yǎng)讀者的抽象設(shè)計能力,算法設(shè)計模塊用于提高讀者運用計算機求解問題的能力,算法分析模塊用于幫助讀者運行用數(shù)學(xué)工具對算法進行客觀分析。同時,本書編寫時也考慮到初學(xué)者所面臨的困難,在算法設(shè)計與描述中,刻意增加了基于源代碼的程序設(shè)計與實現(xiàn)環(huán)節(jié),從而全方位地幫助讀者提高算法設(shè)計與分析實踐能力和理論水平。
