Abstract
Various astronomical observations point towards evidence of dark energy. On e of the most mysterious problems is the coincidence problem: why dark ener gy has become dominant only recently. We present a scenario based on extend ed quintessence models to explain the late-time domination of dark energy w ithout a severe fine-tuning of the initial conditions and model parameters.
