Title: Combinatorial homotopy theory for operads

Abstract: We introduce an explicit combinatorial characterization of the minimal model of the coloured operad encoding non-symmetric operads. In our description, the spaces of operations are defined in terms of hypergraph polytopes and the composition structure generalizes the one of Stasheff's associahedra operad.
