摘要：

We accurately calculate the strong coupling expansion for anharmonic oscillators by means of a robust and stable numerical algorithm. The method applies to any stare and to any anharmonicity degree. By means of the perturbation coefficients, we estimate the location of the branch points that determine the convergence radius of the strong coupling expansion.
