Abstract. This paper introduces a novel approach for the specializa­
tion of functional logic languages. We consider a maximally simplified
abstract representation of programs (which still contains all the neces­
sary information) and define a non­standard semantics for these pro­
grams. Both things mixed together allow us to design a simple and con­
cise partial evaluation method for modern functional logic languages,
avoiding several limitations of previous approaches. Moreover, since these
languages can be automatically translated into the abstract representa­
tion, our technique is widely applicable. In order to assess the practi­
cality of our approach, we have developed a partial evaluation tool for
the multi­paradigm language Curry. The partial evaluator is written in
Curry itself and has been tested on an extensive benchmark suite (even
a meta­interpreter). To the best of our knowledge, this is the first purely
