Yices 2 is an SMT solver that decides the satisfiability of formulas containing uninterpreted function symbols with equality, real and integer arithmetic, bitvectors, scalar types, and tuples. Yices 2 supports both linear and nonlinear arithmetic. Yices 2 can process input written in the SMT-LIB notation (both versions 2.0 and 1.2 are supported). Alternatively, you can write specifications using Y
