可以尝试以下优化:
1. 使用列表推导式代替 for 循环
可以使用列表推导式来代替 for 循环,如下所示:
```python
new_c1_f = [f2.node_id_list[index] for index in range(len(model.demand_id_list)) if len(new_c1_f) < cro1_index and f2.node_id_list[index] not in new_c1_m]
new_c1_b = [f2.node_id_list[index] for index in range(len(model.demand_id_list)) if len(new_c1_f) >= cro1_index and f2.node_id_list[index] not in new_c1_m]
new_c2_f = [f1.node_id_list[index] for index in range(len(model.demand_id_list)) if len(new_c2_f) < cro1_index and f1.node_id_list[index] not in new_c2_m]
new_c2_b = [f1.node_id_list[index] for index in range(len(model.demand_id_list)) if len(new_c2_f) >= cro1_index and f1.node_id_list[index] not in new_c2_m]
```
2. 合并重复的代码
可以将 f1 和 f2 的 nodes_seq 更新的代码合并,如下所示:
```python
new_c1 = copy.deepcopy(new_c1_f) + new_c1_m + new_c1_b
f1.nodes_seq = new_c1
new_c2 = copy.deepcopy(new_c2_f) + new_c2_m + new_c2_b
f2.nodes_seq = new_c2
```
3. 使用 while 循环代替 if 语句
可以使用 while 循环代替 if 语句,如下所示:
```python
while len(model.sol_list) <= model.popsize:
# 代码
```
4. 删除不必要的变量
可以删除不必要的变量 sol_list 和 new_c1、new_c2,如下所示:
```python
model.sol_list = []
while len(model.sol_list) <= model.popsize:
# 代码
```
