Brute forcing a MBT question.

TheCourtJester

When you are forced to brute force a MBT question, what is the best way to go about it? I try and eliminate as much as I can right away. With the ACs that are left, I just negate them and see if I arrive at a contradiction. The problem is that there is more than one way to negate an AC. For example, if the AC says A must be in group 1, then you could put A in group 2,3 etc.. What do you do in this situation?

Anything other than group 1 would be a negation. If the AC says that A must be in group 1 the true negation is:
A can be in something that is not group 1

This includes all other possibilities other than 1.
