主要对检测目标进行建立最小外接矩阵，不仅能够对多目标很好的检测，还能对多目标进行跟踪-Mainly to establish minimum circumscribed matrix of detecting target, not only can the multi-objective good detection, can also for multi-target tracking

Multi-target tracking particle filter, Multi-machine power system simulation and flow calculation, Use of natural gradient algorithm.
