1) fitness average
适应度均值
1.
According to the fitness average and population diversity, a novel adaptive genetic algorithms based on generatio nal gap information is proposed.
针对现有自适应遗传算法无法兼顾群体特性 ,难以稳定地收敛到最优解的问题 ,从种群多样性和适应度均值变化的角度 ,分析了进化停滞或退化的原因 。
2.
Focusing on the problems existed in some adaptive genetic algorithms that cannot take account of population features and are difficult to converge to optimal solution steadily, the reasons of stopping evolution or degeneration are analyzed in view of fitness average and population diversity.
针对现有自适应遗传算法无法兼顾群体特性,难以稳定地收敛到最优解的问题,从种群多样性和适应度均值变化的角度,分析了进化停滞或退化的原因。
2) fitness value
适应度值
3) average fitness
平均适应度
1.
So the population can be divided into two groups based on average fitness:best population and worst population.
鉴于此,根据每代群体的平均适应度将种群分为两部分:优势种群和劣势种群。
4) fitness assignment
适应度赋值
1.
External population maintenance and fitness assignment are the two main parts of multi-objective evolutionary algorithm.
外部种群维护和适应度赋值是多目标进化算法(MOEA)的两个重要部分,该文首先对这两个问题目前已有的处理方法进行了分析,然后提出了基于个体密集距离的外部种群维护方法,并在将所有个体根据Pareto支配关系分成四个层次的基础上,给出了一种由个体密集距离定义的适应度函数,最后将基于个体密集距离的多目标进化算法CMOEA应用于几个常用的测试函数,并和SPEA,SPEA-2进行了比较,计算结果表明CMOEA具有良好的搜索性能。
5) the adaptive window average
自适应窗口均值
1.
Based on his-togram of every frame,we compute the difference of continuous frame,the difference of cumulate frame,the ratio of the frame difference on window,the adaptive window average,the ratio of surpassing average and sliding windows,which are used for shot segmentation.
该算法利用直方图的统计特性,依次求取连续帧差值、累加帧差值及窗口帧差比,并以此确定自适应窗口均值,超均值比率以及多个滑动窗口来进行镜头分割。
6) self-adaptive mean shift
