A bstractWe investigate the possible existence of (meta-)stable de Sitter vacua within $ \mathcal{N} $ = 1 compactificationswithgeneralisedfluxes. Withtheaidofanalgorithminspiredby the method of differential evolution, we were able to find three novel examples of completely tachyon-free de Sitter extrema in a non-isotropic type IIB model with non-geometric fluxes. We also analyse the surroundings of the aforementioned points in parameter space and chart the corresponding stability regions. These happen to occur at small values of the cosmological constant compared to the AdS scale.
