| 6. | Today mixed coniferous forests occupy a wide but well - defined range of climates with mean annual temperatures from three to 13 degrees celsius ( 37 to 55 degrees fahrenheit ) , suggesting that the average yearly temperature for northern alaska during the cretaceous was similar
时至今日，针叶混合林分布广泛，不过其气候型态倒是相当明确，年平均气温介于3 ~ 13 ；想必在白垩纪时，阿拉斯加北部的年平均气温与此相近。 |
| 7. | Chaotic variables have not uniform distribution , and it is worse that chaotic variables are very sensitive to the change of initial value and the defining range of variable ; therefore it is uncertain that the optimal solution can be found . all those shortcomings above bring numerous problems in the process of optimization
通过分析揭示了混沌优化的本质，首先混沌算子在变量定义域上并非均匀分布，所以能否找到最优解是不确定的；再之混沌优化对初值的变化和变量定义域的变化特别敏感，这些给优化过程带来许多难以确定的问题。 |

该算法和混饨一样具有遍历性的特点，且变量均匀分布于定义域，对函数的定义域变化和初值的选定都不敏感，同样也不需要函数连续、可微，对优化对象几乎没有特别要求，从而避兔混池优化算法的缺点。 |
