George, this may be completely dopey, but if one added a slack z to
the objective, and equations<br>
z<=1, z>=a-b, z>= b-a, z=1-c (or some suitable
simplification), that might work..<br>

<div dir="ltr">This might be slightly off-topic, but I don't know
where better to ask. I'm having a hard time expressing
something in ZIMPL linearly. I have two variables a and b. I
want the variable c to be strictly binary and take on the value
of 1 when a and b are equal, and 0 otherwise. Does anyone know
of a good way to express this?
