在多目标多量测环境中, 量测一航迹分配的知识一般不适于跟踪算法。在本文中, 对 量测一航迹分配问题, 采用了严格的概率方法。不象在传统多假设跟踪算法那样, 把量测 分配给航迹相反地, 使用由期望最大化方法导出的最大似然算法估计每次量测属于 每个航迹的概率。这些量测一航迹的概率佑计对于调用随机多假设跟踪算法的多目标跟 踪器是固有的算法在计算上是切实可行的, 因为它既不要求量测一航迹分配的计算, 也 不要求修剪。(The probabilistic multihypothesis tracker (PMHT) is a target tracking algorithm of considerable theoretical elegance.)

In this paper, the dynamic multi-swarm particle swarm optimizer (DMS-PSO) is improved by hybridizing it with the harmony search (HS) algorithm and the resulting algorithm is abbreviated as DMS-PSO-HS. We present a novel approach to merge the HS algorithm into each sub-swarm of the DMS-PSO. Combining the exploration capabilities of the DMS-PSO and the stochastic exploitation of the HS, the DMSPSO-HS is developed. The whole DMS-PSO population is divided into a large number of small and dynamic sub-swarms which are also individual HS populations. These sub-swarms are regrouped frequently and information is exchanged among the particles in the whole swarm. The DMS-PSO-HS demonstrates improved on multimodal and composition test problems when compared with the DMS-PSO and the HS.
