Prolog type inference
WebJan 1, 2005 · This paper presents a type inference system for Prolog. The idea is to describe sets of terms for which the predicates may succeed. We calculate ordered sets of terms … WebA type inference method for Prolog programs is presented to describe a superset of the success set by associating a type substitution (an assignment of sets of ground terms to …

Webtyped-prolog. A basic type system on top of Prolog, along with higher-order clauses. Translates to normal Prolog. Central Features. Typed-Prolog provides the following basic features: An algebraic type system with local type inference, based on Hindley-Milner. This means the following two core components: WebThe information computed by a type inference system allows for several optimizations, such as specialized code generation, use of specific unification modules, suppression of some choice points, or even clause indexing not reduced to the first parameter.

WebThe goal of this assignment is to write a type inference algorithm similar (but simpler) than the one in OCaml/Haskell in SWI prolog. In particular, this program figures out the types of inputs and outputs of functions and type of variables used much like OCaml/Haskell inferes types when it compiles code.

WebA type inference algorithm While in a functional language inferring types requires implementing unification with occurs-check, as shown for instance in [8], this operation is available in most Prologs as a built-in predicate (called unify with occurs check/2), optimized in SWI-Prolog [21] to proceed incrementally, only check- ing that no new ... twf720wpWebOct 11, 1993 · Type inference in Prolog: a new approach.
