Summary/Abstract: In this paper we continue our previous investigation od Akaike simplicity criterion [16] which plays the crucial role in the E. Sober philosophy of science [29] in the context of the modern cosmology. We consider different models of accelerating Universe which describe the current evolution of the Universe. We demonstrate that the generalized Akaike criterion (Bozdogen criterion) distinguishes the very simple standard cosmological model called LCDM (Lamda Cold Dark Matter model) whereas the standard Akaike criterion doesn’t give such unique indication. We demonstrate that the case study of cosmological models may be suitable in searching for more adequate criterion of the simplicity in the context of the philosophy of science.
