optimal population

First it is given to the sufficient conditions that guarantee the existence and global asymptotical stabling of positive periodic solution for the models. Then the maximum sustainable yield per unit time is chosen as management objective, the corresponding optimal population level are determined.

在保证惟一的全局渐近稳定周期解存在的条件下，以单位时间的持久产出作为最终管理目标，得到相应的最佳种群水平和捕获努力量。

Optimal Population Size for Genetic Algorithm Based on Repeated Natural Number Coding

可重复自然数编码遗传算法的最优群体规模

In this paper, the new methods of optimizing genetic algorithm control parameters are presented, including the method of adjusting crossover probability and mutation probability, the dynamic convergence rule and the method of determining the optimal population size.

提出了新的遗传算法控制参数优化策略，包括变异率、交叉率调整策略，动态收敛准则以及二进制编码下最优种群规模的确定方法。
