Auto In Agda
Abstract
As proofs in type theory become increasingly complex, there is a growing need to provide better proof automation. This paper shows how to implement a Prolog-style resolution procedure in the dependently typed programming language Agda. Connecting this resolution procedure to Agda's reflection mechanism provides a first-class proof search tactic for first-order Agda terms. Furthermore, the same mechanism may be used in tandem with Agda's instance arguments to implement type classes in the style of Haskell. As a result, writing proof automation tactics need not be different from writing any other program.
