The other problem in the dissertation reveals that the RBF centers and widths can be evoked by a cooperative-competitive genetic algorithm. Using the well-known credit apportionment problem and niching problem, the different fitness measures in the GA of RBF representation have been studied and the adaptive genetic operators have been given to trade off the problems because of the fitness measure problem.

另外，研究了一种基于全局搜索的遗传算法的带有不同尺度的RBF结构确定的方法，讨论了信度分配问题和小生境问题两个概念，并把两概念应用于基于GA的RBF表示的系统模型中，详细论述了在GA优化过程中，取不同评价函数测量形式，对搜索群体性能的影响，最后提出采用自适应的遗传操作算子来平衡由于评价函数所造成的抑制过度竞争出现早熟问题的方法。
