內(nèi)容簡介

　　無論是目前世界上肆意流行的各類病毒、以癌癥為首的各種疾病，還是某些被發(fā) 現(xiàn)的新物種，人類對低成本、高效、準(zhǔn)確地獲取這些生物的全基因組序列都有著迫切的需求。對于這種大規(guī)模數(shù)據(jù)的分析和處理，僅靠生物學(xué)手段無法高效完成，使用計算機(jī)技術(shù)將有效節(jié)省處理問題的時間和降低經(jīng)濟(jì)成本。本書研究的基因組片段填充算法是在利用生物測序手段獲取基因組片段后，使用計算機(jī)領(lǐng)域的算法思想和技術(shù)，協(xié) 助獲取完整基因組序列的有效手段，具有較好的實際應(yīng)用意義。本書以科研課題“基因組片段填充算法研究”為背景，以設(shè)計各類片段填充算法、分析算法復(fù)雜度、提高算法近似性能比為主要目標(biāo)，對如何使用計算機(jī)算法中的貪婪、局部搜索和匹配等算法思想解決基因組片段填充中的難點(diǎn)問題進(jìn)行了一系列探索。本書涵蓋了基因組片段填充中各類問題的定義、填充原理和算法描述，通過嚴(yán)謹(jǐn) 的理論推導(dǎo)證明了算法的正確性和近似性能比，并通過實例展示了算法的運(yùn)行過程和效果。本書可作為從事基因組序列填充問題研究工作的有關(guān)人員的參考用書。
