抱歉,我在之前的代码中使用了一个名为`calculate_fitness`的函数,但是我没有提供该函数的实现。请在代码中添加一个`calculate_fitness`函数来计算节点位置的适应度(fitness),并根据具体问题定义适应度的计算方式。下面是一个示例的`calculate_fitness`函数:
```python
def calculate_fitness(position):
# 根据具体问题定义适应度的计算方式
# 这里只是一个示例,可以根据实际情况进行修改
fitness = position[0] ** 2 + position[1] ** 2
return fitness
```
请注意,上述代码中的适应度计算方式只是一个示例,你需要根据实际问题进行修改。将上述代码添加到你的程序中,并确保在调用`calculate_fitness`函数之前先定义该函数。这样应该能够解决报错问题。如果还有其他问题,请随时提问。
