Yale ROSE

ROSE is a Yale Computer Science laboratory that focuses on using formal methods to improve software reliability. In particular, we are now working on functional reactive synthesis, symbolic execution engine for Haskell, and verification of configuration files.

Welcome



Lazy counterfactual symbolic execution

G2 is a symbolic execution engine for Haskell, a non-strict, functional programming language.
