表2 四种测试函数

函数名称	测试函数
Sphere函数	$f_{1} = \sum_{i = 1}^{d} x_{i}^{2}$
Rosenbrock函数	$f_{2} = \sum_{i = 1}^{d} [100 {(x_{i + 1} - x_{i}^{2})}^{2} + {(x_{i} - 1)}^{2}]$
Griewank函数	$f_{3} = \frac{1}{4 000} \sum_{i = 1}^{d} x_{i}^{2} - \prod_{i = 1}^{d} \cos (\frac{x_{i}}{\sqrt{i}}) + 1$
Rastrigrin函数	$f_{4} = \sum_{i = 1}^{d} [x_{i}^{2} - 10 \cos (2 π x_{i}) + 1 0]$
