Algorithm 1

Algorithm framework.

	Step 0: (initialization) given the initial point , . Set and .
	Step 1: stop if .
	Step 2: compute the stepsize by an appropriate line search rule.
	Step 3: generate the new iteration point by and compute according to (14).
	Step 4: compute the next direction by (3), set , and go to Step 1.
