Intelligent Warehouse Robot Scheduling System Using a Modified Nondominated Sorting Algorithm

Algorithm 1

Nondominated sorting.

	Input: P (population)
	Output: (stratification results)
(1)	,i = 1;// denotes the size of set of solutions that dominate , i S denotes the set of solutions dominated by
(2)	for
(3)	for
(4)	if then
(5)	elseif then
(6)	end for q
(7)	if then
(8)	end for p
(9)	while // indicates the number of non-dominated layers
(10)	{POP ;
(11)	for
(12)	for , ;
(13)	if
(14)	end for p
(15)	i = i + 1;
