Binary variable in mixed integer linear program
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!
