Algorithm 1

Time allocation and optimization algorithm.

(1)	Calculate with given and ;
(2)	Initialize and such that lies in ;
(3)	Repeat
	(1) ;
	(2) Initialize ;
	(3) Compute using (19). If , go to step 4; if , update using (23)-(24);
	(4) Compute using (23);
	(5) Substitute into (24) and compute using (24);
	(6) Check . If it is satisfied, let ; otherwise, go to step 5;
	(7) Check . If it is satisfied, let ;
(4)	Until, where is a given error tolerance.
