Algebraic Logic Functional language
<language> (ALF) A language by Rudolf Opalla <
[email protected]> which combines
functional programming and
logic programming techniques.
ALF is based on
Horn clause logic with equality which consists of predicates and Horn clauses for
logic programming, and functions and equations for
functional programming.
Any functional expression can be used in a
goal literal and arbitrary predicates can occur in conditions of equations.
ALF uses
narrowing and rewriting.
ALF includes a compiler to Warren Abstract Machine code and
run-time support.
