　　無(wú)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(duì)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(duì)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(wú)法高效完成，使用計(jì) 算機(jī)技術(shù)將有效節(jié)省處理問(wèn)題的時(shí)間和降低經(jīng)濟(jì)成本。本書(shū)研究的基因組片段填充算法是在利用生物測(cè)序手段獲取基因組片段后，使用計(jì)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(shí)際應(yīng)用意義。本書(shū)以科研課題“基因組片段填充算法研究”為背景，以設(shè)計(jì)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(duì)如何使用計(jì)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(wèn)題進(jìn)行了一系列探索。本書(shū)涵蓋了基因組片段填充中各類問(wèn)題的定義、填充原理和算法描述，通過(guò)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(guò)實(shí)例展示了算法的運(yùn)行過(guò)程和效果。本書(shū)可作為從事基因組序列填充問(wèn)題研究工作的有關(guān)人員的參考用書(shū)。
