Is there an incremental SMT solver or an API for some incremental SMT solver where I can add constraints incrementally, where I can uniquely identify each constraint by some label/name?
The reason I want to identify the constraints uniquely is so that I can drop them later by specifying that label/name. The need for dropping constraints is due to the fact that my earlier constraints become irrelevant with time. I see that with Z3 I cannot use the push/pop based incremental approach because it follows a stack based idea whereas my requirement is to drop specific earlier/old constraints. With the other incremental approach of Z3 based on assumptions, I would have to perform check-sat of the format "(check-sat p1 p2 p3)" i.e. if I had three assertions to check then I would require three boolean constants p1,p2,p3, but in my implementation I would have thousands of assertions to check at a time, indirectly requiring thousands of boolean constants. I also checked JavaSMT, a Java API for SMT solvers, to see if the API provides some better way of handling this requirement, but I see only way to add constraints by "addConstraint" or "push" and was unable to find any way of dropping or removing specific constraints since the pop is the only option available.
I would like to know if there is any incremental solver where I can add or drop constraints uniquely identified by names, or an API where there is an alternative way to handle it. I would appreciate any suggestion or comments.
