Yes indeed : a starting point here : Sarah Denoux, Yann Orlarey, Stéphane Letz, Dominique Fober, CALCUL
D’UNE EXPRESSION FAUST ÉQUIVALENTE À PARTIR D’UN GRAPHE D’APPLICATIONS
http://jim2016.gmea.net/actes
(although in french)
And in function here : http://faust.grame.fr/faustplayground/ when you export the final equivalent
patch.
