In my previous post I have been wrong in identifying the constraint. What I actually need is something like XOR operator, not AND operator, i.e. z[i] = p[i] xor p[i+1]
There are 8 elements of {0, 1}**3. In this case, 4 of them need to be eliminated. Just add 4 constraints. -- Michael address@hidden "Pessimist: The glass is half empty. Optimist: The glass is half full. Engineer: The glass is twice as big as it needs to be."
