Bianchi type-I cosmological models are discussed in the Bergmann-Wagoner-Nordtvedt scalar-tensor theory where both the so-called cosmological constant Λ and the coupling parameter ω are taken to be functions of the scalar field φ. Exact solutions are obtained in Dicke’s revised units assuming a very simple relationship between Λ and φ. The properties of the models are discussed in special cases.
