The RISC ProofNavigator: a proving assistant for program verification in the classroom
Full recordShow full item record
This paper gives an overview of the RISC ProofNavigator, an interactive proving assistant for the area of program verification. The assistant combines the user-guided top-down decomposition of proofs with the automatic simplification and closing of proof states by an external satisfiability solver. The software exhibits a modern graphical user interface which has been developed with a focus on simplicity in order to make the software suitable for educational scenarios. Nevertheless, some use cases of a certain level of complexity demonstrate that it may be also appropriate for various realistic applications.
