Alternatively, if only I could find a way that I can make a list of binary symbolic variables x[0] , ..., x[n-1] that I can work with over GF(2), this would give me something to go from. While this is somewhat unrelated, would you know how to accomplish this?
2015-09-28 08:58:51 +0200	asked a question	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!
