The Simulated Annealing, SA, technique is applied to maximize the magnitude of external hydrostatic pressure for bowed out shells for which, the shape of the meridian is sought. A global maximum offers a 40% increase in load carrying capacity over the mass equivalent cylindrical shell of the same mass whilst the SA heuristic proves to be computationally affordable.
