The RISC ProgramExplorer
July 21, 2020: RISC ProgramExplorer 2.26 (fixed spurious "message corrupt" in proof browser)
The RISC ProgramExplorer is a computer-supported program reasoning
environment for a simple imperative programming language "MiniJava"; it
incorporates the RISC ProofNavigator
as a semi-automatic proving assistant. The environment has been
developed mainly for educational purposes (see this paper
for a sketch of the main ideas).
The software runs on computers with
x86-compatible processors under the GNU/Linux operating system; it is
freely available under the terms of the GNU

RISC ProgramExplorer is installed in the RISC environment.
To start the software (respectively the included new version
of the RISC ProofNavigator), execute
To start the software, login as user "guest" with password "guest", double-click the "Terminal" icon, then execute "cd examples-ProgramExplorer-CVC3" and "ProgramExplorer &". As a small demo, double-click the class "Factorial" in the left panel, then right-click the method "fac" and select "Show Semantics" to investigate the semantics of the method as a relation on program states.
