The local decision space partitioning is given in the sense of maximum Bhattacharyya distance criterion. The optimality and the non-triviality of the partitioning scheme are proved. The reasonability of using Bhattacharyya distance as partitioning criterion is analyzed. The simulation results show that the partitioning method based on Bhattacharyya distance criterion is superior to that based on J-diversity criterion.

研究了基于 Bhattacharyya 距离准则的决策空间优化划分问题，求出了在 Bhattacharyya 距离最大意义下的决策空间划分方法，证明了这种决策空间划分方法的最优性和非退化性，分析了选择 Bhattacharyya 距离作为划分准则的合理性，并进行了计算机仿真比较，结果表明基于 Bhattacharyya 距离准则的决策空间优化划分优于基于最大 J-散度准则的决策空间划分。
