local minimum

The problem of trapping into the local minimum is solved, which is inherent with the learning algorithms-based on the BP principle by weight strategy.

但是BP网络极容易陷入局部极小(值),应用加权策略解决了此问题。

On the other hand, the method in this paper can avoid the local minimum efficiently by adding the number of the particles.

并将仿真结果与BP网络进行比较,仿真数据表明,PSO算法在叠代次数、函数逼近误差、网络性能方面均比BP网络有着显著的提高,且在粒子数目较大的情况下能有效避免BP网络无法避免的局部极小(值)问题。
