A recently developed renormalized strong coupling expansion [E. J. Weniger, Ann. Phys. (N.Y.) 246, 133 (1996)] is employed to compute the coefficients of the standard strong coupling expansion for the ground state energy of the quartic, sextic, and octic anharmonic oscillator. This approach is very simple, both conceptually and technically, and produces more accurate results than previously used techniques which were in most cases applied to the quartic case only.
