Dijkstra monad

WebEach point in the lattice is a monad of predicate transformers (aka a Dijkstra monad) Key idea, in three steps: Fix the bottom and top of the lattice: .wp and .wp. In between, partition the effects as needed, defining a WP calculus for each sub-effect and monad morphisms to partially order effects E.g., .wp.wp.wp WebThis paper advocates a new verification methodology for higher-order stateful programs, based on a new monad of predicate transformers called the Dijkstra monad. Using the Dijkstra monad has a number of benefits. First, the monad naturally yields a weakest pre-condition calculus.

WebFor defining correct monad transformers, we propose a language inspired by Moggi's monadic metalanguage that is parameterized by a dependent type theory. We also develop a notion of algebraic operations for Dijkstra monads, and start to investigate two ways of also accommodating effect handlers. WebDijkstra monads.
