About cvc5

cvc5 is an efficient open-source automatic theorem prover for Satisfiability Modulo Theories (SMT) problems. It can be used to prove the satisfiability (or, dually, the validity) of first-order formulas with respect to (combinations of) a variety of useful background theories. It further provides a Syntax-Guided Synthesis (SyGuS) engine to synthesize functions with respect to background theories and their combinations.

cvc5 is the successor of CVC4 and is intended to be an open and extensible SMT engine. It can be used as a stand-alone tool or as a library, with essentially no limit on its use for research or commercial purposes (see license). To contribute to cvc5, please refer to our contribution guidelines.

cvc5 is a joint project led by Stanford University and the University of Iowa.

Guidelines For Fuzzing cvc5

The development team of cvc5 is committed to ensuring that its core usage model (without experimental options) is extremely robust. At the same time, our team is small and we have to set priorities, including prioritizing user bugs over fuzzer bugs.

When applying fuzzing techniques to cvc5, we ask you to follow these guidelines.
