local convergence

With the improved adaptive genetic algorithm, which can avoid local convergence, the optimal solution can be ger.

基于这种改进的自适应遗传算法，就不会使种群产生局部收敛，可以在全局寻找最优解。

Through optimally selecting a group of virtual standard samples off-line, this algorithm can fulfill rapid and accurate on-line fault recognition, so it can effectively solve the problem of local convergence with FCM.

该方法通过离线优选虚拟标准样本，达到快速、准确在线识别故障的目的，很好地解决了FCM算法经常收敛到局部极值点的问题。

We lay particular emphasis on analysis of global and local convergence and rate of convergence.

侧重于收敛的速率和整体、局部分析。

The method of judging the local convergence by the variance of the population's fitness and reducing the searching space of variable optimized is proposed, which enhances the searching efficiency.
