Algorithm 1

The general framework of the proposed algorithm.

(1)	Initial estimation , final value , initial value , reduction factor ,
(2)	whiledo
(3)	with as the initial value, solve the problem:
(4)	ifthen
(5)	stop iteration, output
(6)	else
(7)	update the penalty factor:
(8)
(9)	end if
(10)	end while
