  1. A modified genetic algorithm ( mga ) framework was developed and applied to the flowshop sequencing problems with objective of minimizing mean total flowtime. to improve the general genetic algorithm routine, two operations were introduced into the framework. firstly, the worst points were filtered off in each generation and replaced with the best individuals found in previous generations ; secondly, the most promising individual was selectively cultivating if a certain number of recent generations have not been improved yet. under conditions of flowshop machine, the initial population generation and crossover function can also be improved when the mga framework is implemented. computational experiments with random samples show that the mga is superior to general genetic algorithm in performance and comparable to special - purpose heuristic algorithms. the mga framework can also be easily extended to other optimizations even though it will be implemented differently in detail

    提出了一個改進遺傳演算法的結構,並且應用於帶有目標是最小平均總流程時間的流水調度排序中.為了改進一般遺傳演算法的程序,兩個新的操作被引進到這個操作中.這兩個操作為: 1 )過濾操作:過濾掉在每一代中的最壞的個體,用前一代中的最好的個體替代它; 2 )培育操作:當在一定代數內演算法不改進時,選擇一個培育操作用於培育最有希望的個體.通過大量的隨機產生的問題的例子的計算機實驗顯示出,提出的演算法的性能明顯好於一般遺傳演算法,並且和此問題的最好的專門意義的啟發式演算法相匹配.新的mga框架很容易擴展到其它最優化當中,只是實施的詳細的步驟有所不同
  2. The nucleic acids of the all influenza viruses conducted in the research were extracted from the viruses propagated in specific - pathogen - free chicken embryos. all of the eight segments were amplified by rt - pcr, and the purified pcr products were done cycle sequencing with specific primers, furthermore, the sequencing products were purified and run gel on abi prism 377 dna sequencing machine. the specific primers of the eight genes for pcr and cycle sequencing were designed using the ohgo ( 4. 0 version ) and genedoc ( 2. 3 version ) software
