Szukana fraza: [Abstract = "To obtain smooth solutions to ill\-posed problems, the standard Tikhonov regularization method is most often used. For the practical choice of the regularization parameter \? we can then employ the well\-known L\-curve criterion, based on the L\-curve which is a plot of the norm of the regularized solution versus the norm of the corresponding residual for all valid regularization parameters. This paper proposes a new criterion for choosing the regularization parameter \?, based on the so\-called U\-curve. A comparison of the two methods made on numerical examples is additionally included."]
