Abstract
An algorithm is proposed for the determination of the asymptotics of a sum of a perturbation series from the given values of its coefficients in the strong-coupling limit. When applied to the \Phi^4 theory, the algorithm yields the \beta(g)\propto g^\alpha behavior with \alpha\approx 1 at large g for the Gell-Mann - Low function.
