表1 基准测试函数

函数表达式	取值范围	最优解
$f_{1} = \sum_{i = 1}^{n} \| x_{i} \| + \prod_{i = 1}^{n} x_{i}$	[-10, 10]	0
$f_{2} = \sum_{i = 1}^{n} [100 {(x_{i} + 1 - x_{i}^{2})}^{2} + {(x_{i} - 1)}^{2}]$	[-30, 30]	0
$f_{3} = \frac{1}{4 000} \sum_{i = 1}^{n} x_{i}^{2} - \prod_{i = 1}^{n} \cos (\frac{x_{i}}{\sqrt{i}}) + 1$	[-600, 600]	0
