Two different subjects today

[ngoctp29121982]

Hello Liviu! I have a problem that I can't solve when working with FET: I have 6 subjects and divided into 2 groups, Group 1: Math, Physics, Chemistry; Group 2: Literature, English, Biology. I want Math-Literature or Math-Biology or Math-English to not appear in a morning-afternoon class. That is, 1 subject in group 1 and 1 subject in group 2 do not appear in the same class (morning or afternoon).

Hello, ngo,

Unfortunately, as often happens with your posts, I don't understand.

Also, it is best to allow also others to answer.

Edited: if you mean you don't want pairs (Math, Literature)... on the same day for a students set: for half-days, it is easy: add two constraints students min gaps between ordered pair of activity tags. Unfortunately, for real-days I see no solution, other than min 1 days between each subjects pair.
