Hi all,

I'm struggling with the translation of "cannot."

In an In/Out game if A & B "cannot" be together, then:

- is A <--> not B and B <--> not A (or rather, is a biconditional relationship necessarily created)? because they are always apart/never together?

In a Grouping game, if A & B "cannot" be together, then:

- is a negate necessary the only result? - is A ---> not B and B --> A?

Hi @anjkumar87,

•

In/Out GameIf A and B

cannot betogether and A and B have to be in the In group or the Out group, then you have to represent it as A <---> /B.•

Grouping GameThere are more than two groups with items that are not repeatable, and A and B

cannot betogether, you should represent it as A ---> /B because this means that if A is in one group, B cannot be in that group. There is no particular Out group. We look at each group as "In group", and we see that if A is in a group, B has to be in other groups.This discussion might clear things up:

Do you have the test and game number?
