Painless programming combining reduction and search: design principles for embedding decision procedures in high-level languages

Abstract

We describe the Funlogic system which extends a functional language with existentially quantified declarations. An existential declaration introduces a variable and a set of constraints that its value should meet. Existential variables are bound to conforming values by a decision procedure. Funlogic embeds multiple external decision procedures using a common framework. Design principles for embedding decision procedures are developed and illustrated for three different decision procedures from widely varying domains.
