average fitness meaning in English

平均适合度

When solving independent problems , the mathematical analysis shows that when a schema whose fitness is higher than the overall average fitness , the schema ' s exponential increase index of trials allocated in the next generations of coevolutionary genetic algorithm ( cga ) is higher than that of csga
数学分析表明，对于独立多问题，共同进化算法采用按比例选择策略时，高于平均适应值的模式的逐代递增指数高于传统单种群遗传算法，说明共同进化算法的效率高于传统的单种群遗传算法。
The evolution laws of structural weight , the best optimum fitness , average fitness , maximum nodal stress and displacement with increasing generations are discussed . and multi - result fact of the topology optimization can be obtained by ga - fem . the research results in this thesis show that the developed method is successful in the topology optimization for 2d continuum structures under multi - load and multi - constrain conditions
上述工作表明，本文ga ? fem可以实现多载荷、多约束条件下平面连续结构拓扑优化，与eso等优化方法获得的优化结果相比，本文的优化结果不存在单元铰接和不连续单元，优化结构多样，质量更小，效果更优。
