Various methods to arrive at results such as Kontsevich's formula for plane rational curves, or Caporaso-Harris's formula for plane curves of any genus, are illustrated on concrete examples It will appear on the Proceedings of the European Congress of Mathematics, Budapest 1996.Plain-Tex file, 14 pagesAlgebraic Geometrytext
