genetic bottleneck 解釋
種群遺傳瓶頸效應
  • genetic : adj. 1. 遺傳（學）上的。2. 發生的，發展的；創始的。adv. -ically
  • bottleneck : n. 瓶頸口；（交通易堵塞的）隘道，狹口；〈美國〉（特指生產中的）妨礙進度的因素，薄弱環節。2. vt. 阻礙，限制。3. vi. 交通堵塞。4. adj. （街道等）狹隘的。
  1. There are very low genetic variation existing in the population due to bottleneck events and small effective population size

    由於瓶頸效應和有效種群小，使得該物種種群遺傳多樣性貧乏。
  2. Genetic research experts agreed that developments in genetics will profoundly effect medicine for the better, they could also cause a significant bottleneck for health care organizations

    基因研究專家認為遺傳學方面基因研究的進步能夠顯著改進用藥狀況，它們也能夠使得現在的醫療保健機構處于上下兩難的瓶頸狀態。
  3. After analyzing the characteristic of the parallel processing system, some problems about design missile - carrying processing system are pointed out ; network in the parallel processing system has become bottleneck and affect the performance of system, so the processing efficiency is analyzed in a multiprocessor system based on cluster - bus and some rules in designing the network in the multiprocessor system are brought out ; genetic algorithm is used for scheduling in the multiprocessor system, and a scheduling algorithm is described to suit arbitrary number of tasks, unequal task processing time, arbitrary precedence relation among tasks and arbitrary number of parallel processor, so that the schedule length will be minimized ; finally, an atr algorithm is mapped to a ring multiprocessor system, and a block diagram using dsp device is constructed. in chapter 4, the study is performed on real - time system hardware realization of atr. tms320c80 is selected as the kernel processor in multiprocessor system

    為此，對一種由常用的dsp晶元組成的多處理器系統的處理器利用率進行了分析，提出了多處理器系統互連網路設計的基本原則；本章使用遺傳演算法作為實現多處理器調度的工具，提出了一種新的任務調度演算法，該演算法主要是為了解決在任務數任意、任務計算時間不相等、任務前趨關系任意、以及任務間存在通信和考慮任務存貯器要求的情況下，如何優化任務在各個處理器上的分配和執行順序，使得多處理器系統總的執行時間最小；最後對一個目標識別演算法進行了硬體實現優化分析，根據分析結果，將演算法映射到由dsp晶元組成的環形網路連接的處理器拓撲結構上，得到了多處理器系統的原理框圖。
  4. Taking account of the bottleneck - path which results in the congestion of network and analyzing the reason of unbalanced load with the link cost redefined, a genetic algorithm is presented to solve the problem of multicast routing

    摘要針對網路的瓶頸路徑易造成網路擁塞的現象，分析了鏈路負載不平衡的原因，重新給出鏈路代價定義，提出一種遺傳演算法求解該類組播路由問題。
