Binary variable in mixed integer linear program

savecancel

Hi asksage!

I'm using the MixedIntegerLinearProgram class to model a mixed integer linear program. I am using binary variables created e.g. by x = mip.new_variable(binary=True, name="x"). Now, I am using this variable e.g. by x[0] or x[3,2]. When I create a constraint using sums over binary variables, this sum is in the integers, as it should be. However, I am wondering if there is another way to easily add such variables together over GF(2) such that e.g. x[0] + x[0] disappears from the equation?

I ask because my model is too complicated to write by hand, so I am using some auxiliary methods to construct constraints and variables, etc.

I hope you can help me out!
