Abstract
. Schema-based transformational systems maintain a library of logic program schemata which capture large classes of logic programs. One of the shortcomings of schema-based transformation approaches is their reliance on a large (possibly incomplete) set of logic program schemata that is required in order to capture all of the minor syntactic differences between semantically similar logic programs. By defining a set of extensible logic program schemata and an associated set of logic program transformations, it is possible to reduce the size of the schema library while maintaining the robustness of the transformational system. In our transformational system, we have defined a set of extensible logic program schemata in #Prolog. Because #Prolog is a higher-order logic programming language, it can be used as the representation language for both the logic programs and the extensible logic program schemata. In addition to the instantiation of predicate variables, extensible logic program sc...
