MEA-CNDP: A Membrane Evolutionary Algorithm for Solving Biobjective Critical Node Detection Problem

Algorithm 6

Membrane-to-subproblem matching.

	Input: P (current membrane population), NoF (the mark of main objective function)
	Output: P (membrane population)
(1)	S ← ;
(2)	for each m in P do
(3)	Remove the upper bound vector of m and add it to S;
(4)	while S is not empty do
(5)	← Randomly select a upper bound vector from S;
(6)	for each miin P do
(7)	← Calculate the value of membrane mi to the (NoF + 1)-th objective function;
(8)	← ;
(9)	k ← ;
(10)	Remove the upper bound vector of membrane mk;
(11)	Add the upper bound vector to membrane mk;
(12)	Delete the upper bound vector of S;
(13)	return P;
