Abstract
Some Bianchi type III string cosmological models for perfect fluid distribution with an alternate approach are discussed, assuming a condition between energy density and string tension density. We have also assumed a relation between metric potentials to get deterministic solution. The physical and geometrical aspects of the models are also discussed.
