  Stable vacua obtained from isotropic tori compactification might not be fully
stable provided the existence of runaway directions in the Kaehler directions
of anisotropy. By implementing a genetic algorithm we report the existence of
explicit flux configurations leading to stable de Sitter and Anti- de Sitter
vacua, consisting on Type IIB compactifications on a 6-dimensional anisotropic
torus threaded with standard and S-dual invariant non-geometric fluxes in the
presence of orientifold 3-planes. In all dS vacua the masses of the complex
structure moduli are heavier than the Hubble scale suggesting that the
axio-dilaton and Kaeahler moduli are natural candidates for small-field
inflation. In the way, we also report new solutions on isotropic and
semi-isotropic tori compactifications. Finally, we observe that, since all our
solutions are obtained in the absence of solitonic objects, they are good
candidates to be lifted to stable solutions in extended supersymmetric
theories.
