Unfortunately, I’m not familiar enough with LP to know what you mean by that statement.

However, I didn't (and still don't) see a way to create a constraint in the optimization class that will let me use anything other than a number for the right hand side. Do you know if this library has this ability?

This reduces your constraints to a much simpler form Sum_j A_ij = 0 A_ij = A_ji Sent from my iPhone
