Efficient Multitask Scheduling for Completion Time Minimization in UAV-Assisted Mobile Edge Computing

Algorithm 2

An iterative algorithm for problem (15).

(1)	Initialize, ,
(2)	Repeat
(3)	Obtain the optimal solution of , and by Algorithm 1;
(4)	Find the optimal scheduling mode, ;
(5)	Update the initial position of the UAV for the next task-group:
(6)	if or then
(7)	;
(8)	else
(9)	;
(10)	Update the time for completing the previous task-groups:
(11)	Update ;
(12)	Until a maximum number of iterations has been reached (i.e., )
(13)	Now is the minimum time to complete all the tasks.
