Previous studies have demonstrated that if the fixed parameterμis chosen improperly，the cost of computation will increase greatly.In our algorithm，we adopt the adaptive update strategy for the penalty parameterμ.Whenμk increases toρμ，the convergence rate is improved.Whereρ>1 is a constant which can guarantee both optimality and fast convergence by selecting it properly.
