Interpolating bit-vector arithmetic constraints in MCSAT

  title={Interpolating bit-vector arithmetic constraints in MCSAT},
  author={St'ephane Graham-Lengrand and Dejan Jovanovic},
We present an interpolation mechanism for a fragment of bit-vector arithmetic. Given a conjunction of constraints under one existential quantifier, and given an interpretation of its free variables that falsifies it, we produce a quantifier-free interpolant of the constraints and of the interpretation: the interpolant is implied by the constraints and it is still falsified by the interpretation. The interpolant explains why the interpretation does not satisfy the constraints. This can be used… Expand
