I have some binary variables in my formulation. I see that when I extract node relaxation values using cbGetNodeRel(), sometimes, these binary variables take values exceeding 1. I don't expect these variables to be binary but at least between 0 and 1. Also, these node relaxation values are violating some constraints. Is this common? If yes, why is it happening? If no, can you tell me where I am going wrong?
