Coq includes a Turing-complete language for writing programs that manipulate proof states, such that, by construction, one of these programs can never claim to have proved a goal when it really hasn't. We will show how many examples of certified programming can be completed by writing custom decision procedures that are robust to changes in program implementation and specification. Proofs in this style are naturally decomposed into pieces that can be read and understood in isolation, free of deep hierarchical structure, a major victory for maintainability. -We expect to spend almost all of class time on example programs and proofs, with the class working together to build the solutions in a live Coq environment. We'll draw examples from a variety of domains, based on audience interest. We'll probably spend a good amount of time on applications related to certified programming language tools, since they provide a great stress test for reasoning about programs with complicated specifications, and also because the instructor thinks they're cool. Most of the class, though, will be based on case studies suggested by participants based on their own research and other interests. +We expect to spend almost all of class time on example programs and proofs, with the class working together to build the solutions in a live Coq environment.
