A real Eldarica Tree	A reachability tree created by Eldarica for the mutual exclusion protocol with arbitrary number of clients

Eldarica Eldarica is a predicate abstraction engine. It generates the abstract reachability tree (ART) using lazy abstraction with Cartesian abstraction. It uses the Princess interpolating prover to refine the set of predicates. Besides Princess, Eldarica is able to use Z3 as a theorem prover for constructing an abstraction of the program. For the Z3 connection, Eldarica uses ScalaZ3.

Eldarica can take as input a subset of Scala, or logical representations such as Numerical Transition Systems and Horn clauses.
