Z3 2.0 brings you a SMT solver which combines several theory solvers into a combined framework. It can be used to prove theorems and find counter-examples for non-theorems.Z3 is a new high-performance theorem prover being developed at Microsoft Research. Z3 supports linear real and integer arithmetic, fixed-size bit-vectors, extensional arrays, uninterpreted functions, and quantifiers. Enhancements:New features:Parallel Z3. Thanks to Christoph Wintersteiger there is a binary supporting running multiple instances of Z3 from different threads, but more interestingly, also making use of multiple cores for a single formula.Check Assumptions. The binary API exposes a new call Z3_check_assumptions, which allows passing in additional assumptions while checking for consistency of the already asserted formulas. The API function returns a subset of the assumptions that were used in an unsatisfiable core. It also returns an optional proof object.Proof Objects. The Z3_check_assumptions returns a proof object if the configuration flag PROOF_MODE is set to 1 or 2.Non-linear arithmetic using Groebner basis computation.Recursive data-types. The theory of well-founded recursive data-types is supported over the binary APIs. It supports ground satisfiability checking for tuples, enumeration types (scalars), lists and mutually recursive data-types.Main changes to the API:The names of the basic objects exposed by Z3 have been renamed from type to sort.The managed API uses the type-safe context by default. Using the type-safe context, every term, sort and function declaration is managed in a .NET object. The non-type safe version (RawContext) uses integer pointers for these different types.
