An Efficient Nelson-Oppen Decision Procedure for Difference Constraints over Rationals
2006
Electronical Notes in Theoretical Computer Science
Nelson and Oppen provided a methodology for modularly combining decision procedures for individual theories to construct a decision procedure for a combination of theories. In addition to providing a check for satisfiability, the individual decision procedures need to provide additional functionalities, including equality generation. In this paper, we propose a decision procedure for a conjunction of difference constraints over rationals (where the atomic formulas are of the form x ≤ y + c or x
