Abstract
The standard model of cosmology is investigated using time dependent cosmological constant and Newton's gravitational constant . The total energy content is described by the modified Chaplygin gas equation of state. It is found that the time dependent constants coupled with the modified Chaplygin gas interpolate between the earlier matter to the later dark energy dominated phase of the universe. We also achieve a convergence of parameter , with minute fluctuations, showing an evolving . Thus our model fairly alleviates the cosmic coincidence problem which demands at present time.
