random genetic mutation 解釋
隨機基因突變
  • random : n 〈罕用語〉胡亂行為，偶然的[隨便的]行動[過程]。adj 1 任意的，胡亂的，隨便的；（話等）信口亂說的...
  • genetic : adj. 1. 遺傳（學）上的。2. 發生的，發展的；創始的。adv. -ically
  • mutation : n. 1. 變化,變異,更換；【生物學】突變；突變種；【語言學】母音變化；【音樂】（提琴的）變換把位；變聲；【法律】讓受。2. （人世的）浮沉,盛衰。
  1. Neutral mutation - - evolution at the molecular level is primarily determined by mutational input and random genetic drift, rather than by natural selection

    天然突變- -演化過程中在分子的層次上主要是經由隨機的基因流而決定，並非藉由天擇所影響。
  2. The rest mutations in pp38 and pp24 are at random. sequence analysis also shows the first 195 nuclear acids of pp38 and pp24 are the same except for the 81 site ( g / c ), but this mutation does not cause the change of amino acid. we regard this as a genetic marker connecting with geography in the evolution of mdv but not related to isolated time and pathotype of different strain of mdv i

    對pp24基因和pp38基因進行同源性比較分析的結果表明，絕大多數毒株二者的前195個核苷酸完全一致，不同毒株間的第81位核苷酸的差異（ g / c ）並不引起編碼的氨基酸變化，僅僅與地域分佈有關，這很可能是mdv在長期病毒衍化過程中形成的地域性遺傳標志，而與病毒的分離年代及mdv的致病型等因素無關。
  3. In the thesis, the key technical problems utilizing genetic algorithm and random method to design any - cast routing algorithms are explored. we designed and realized the any - cast routing algorithm based on genetic algorithm. resolved the problems concerned in the algorithms, such as the code model, the original genus selection, the fitness function, the crossover strategy, the mutation regulation, and the algorithm ' s convergence, avoidance of dead loop etc. aim at different network scales we propose two any - cast routing algorithms

    論文探討利用遺傳演算法和隨機方法研究選播路由演算法的關鍵技術問題，設計實現了基於遺傳演算法的選播路由演算法，解決了演算法中的編碼模式、初始種群選擇、適應度函數、交叉策略、變異規則，以及演算法的收斂、路由死循環的避免和負載均衡等問題。
