In International Congress of Mathematicians. Madrid.http://hdl.handle.net/10198/1963A computer algebra package, for the automatic computation of variational symmetries in optimal control, was recently developed by the authors [2,3]. Now we present a graphical user interface which permit to interact, in a point-and-click environment, with all the previous symbolical tools.engconference object
