Before revision:  We extend the famous EXTRA and DIGing methods with accelerated variance reduction (VR), and propose two methods , which require the time of O(( \sqrt{n\kappa_s +n)\log1{\epsilon})
After revision:  We extend the widely used EXTRA and DIGing methods with accelerated variance reduction (VR), and propose two methods , which require the time of O(( \sqrt{n\kappa_s +n)\log1{\epsilon})
