geatpy能否提供类似Gurobi,Cplex优化器那样的接口,可以先读取lp或MPS类型的模型文件,然后求解问题;
如read(test.lp),读取对应的模型文件,然后使用geatpy的遗传算法进行求解!谢谢!

你好。之前在github已更新修复了此问题。但pip安装包没有同步更新。

多种群的选择函数存在bug;
我在程序中设置了对每个种群个体的选择数量要大于当前种群的50%(也即MSel=0.5,NSel=300),共计3个种群;
执行mselecting函数后,得到的子代种群数量并没有达到每个种群数量的50%以上,如下图所示:第三个种群初始个体数量为16个,按照设置的MSel=0.5,选择后第三个种群数量起码要达到8个以上,但是结果只选择了1个。同理第二个种群的选择结果…
