Hi,

My name is Zvonko.

I have a question regarding binary variables in GLPK.

Is it possible to implement a kind of a boolean addition to binary variables.

For example:

Let X, Y and Z be binary variables.

X and Y ara inputs, Z is a result.

X + Y = Z

Such that

0 + 0 = 0

0 + 1 = 1

1 + 0 = 1

1 + 1 = 1

So this would be sometning like a logical .OR. addition?

Many thanks

Regards
