EXAMPLE : An appropriate algorithm should tell me that * ****** * * * *******************? * * ** * ******* ************ * ******************* are two sets of curves, where the first consists of two curves connecting at '?' and the second is only one curve -- together with an estimate PHI(u) = { x(u), y(u) } of the parametrical description of all curves.
