Hello Liviu!
My school has a natural science subject (Science Science) of 4=1+1+2 corresponding to physics = 1, chemistry = 1 and biology = 2 corresponding to three teachers: A, B and C
I want to create a constraint that the lessons of the week are in order: Physics-Chemistry-Biology respectively on three different days. Does the fet have that constraint? I looked and didn't find it. Can you help me. Thank you!
I think you can use two constraints two activities are ordered. And raise min 1 days between activities to 100%.
Am I doing this right? Can you see the attached file for me?
Attached file I put below
please create an example file for me
I don't see what is so difficult. I told you very clearly how to solve this. A, B, C, create two activities ordered A, B, then two activities ordered B, C. And min 1 days between A, B, C, 100%.
If I separate the Natural Science subject into 3 subjects: Teacher A teaches Physics (1); Teacher B teaches Chemistry (1) and teacher C teaches Biology (2=1+1). I want to give Physics on Monday, Chemistry on Tuesday and born on Wednesday, May 4, and 5?

I don't understand this phrase, it contains maybe some typos? Could you check it, please?
If I have Teacher A who teaches Physics (1); Teacher B teaches Chemistry (1) and Teacher C teaches Biology (2=1+1). I want to randomize the Physics and Biochemistry classes in order of days of the week: For example Physics on Monday, Chemistry on Tuesday, Born on Wednesday and Friday....
Instead of "Born" do you mean "Biology"?
Add 3 constraints two activities are ordered, and add a min 1 days between activities with 100% for the 4 (sub)activities.
Attached an example.
You might use "two sets of activities are ordered" for easier input, but I am not sure.
Thank you Liviu
i will try it
I did it, thank you very much. but there are too many constraints because there are many classes that need to be ordered in the physical-chemical-biological subjects. Is there any faster way? for example import data from csv file for example
As I told you, maybe 2 constraints two sets of activities are ordered: 1) (All PH, All CH), 2) (All CH, All BI).
In my opinion just create a "two groups of activities sorted" constraint to make input easier for the user? Can you fix it in the new version
It is there: two sets of activities are ordered.
But I can't try it, it seems that the binding is not correct
Add two constraints. On the first, the first set is all PH, the second set is all CH. How doesn't it work?
Did you see that I added the correct binding? I find it too much manipulation in these two constraints, because there are many classes that have to be arranged in the order Physics-Chemistry-Biology. I attached the file below
Not two activities are ordered, but two sets of activities are ordered. It is the constraint below it in the menu.
I have attached the file below, do you see it correctly? If not correct, please correct me. thank you
No; like in my attachment.
Two Constraints is time consuming. Is it possible to use only one binding two groups of ordered operations?
You have 3 groups of activities, so you need 2 constraints. I don't understand.
Is it okay to use only one "two ordered groups of operations" constraint?
No, because you have A, B, C, and to order A>B>C you need 2 constraints.
I understand your. thank you.
Good night
OK, good night!
