Hi, i try to run it but when I use 18 machines, it can't run

[sebashc3712]

Hi, @dinhngocbao1991

Do you get any error or is it taking too long??

[dinhngocbao1991]

I'm using your program to solve my problem including 15 machine, 23 job from 1 to 8 progress but I couldn't find direct solution. Could you help me solving my problem by your genetic algorithm.

[sebashc3712]

Could you send your code please??

I ran as your guide, just expand it. However, i couldn't find a appropriate solution.

[dinhngocbao1991]

Please help me as much as you can

[sebashc3712]

Are you getting an infeasible solution as final solution??

[dinhngocbao1991]

Yes, it is not right with scheduling problem

[sebashc3712]

How many generations do you have?? You could try putting more generations. Your problem is very big and the 500 generations by default maybe is too low. Remember that this algorithm improve with each new generation. It's an intelligent search-algorithm

[dinhngocbao1991]

I just use 500. As far as you know, how many I should with my problem?

[sebashc3712]

I don't know you real problem but trying to solve scheduling problem for 15 machines is pretty big. I have only read that in academic researches.

What you can do is to group machines or operations in order to obtain an smaller number in these two variables. It's like you're implementing work-cells in real life. With less machines and operations you are making the problem easier to solve.

If you can't do that, try with AT LEAST 2000 generations. But I would recommend to model the problem better first

[dinhngocbao1991]

I see your code so pretty smart and i wanna use it your logic in my problem. As you mentioned, your code is not problem. However, i have to rise numbers generation more so that find suitable solutions. It will take time for computer run.

[dinhngocbao1991]

I have try but i couldn't find a suitable solution
