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

Algorithm 5

UpdateIP. Update the membrane inherited pool.

	Input: Pi, P (current membrane population), NoF (the mark of main objective function),
	Output: IP (the membrane inherited pool)
(1)	for each miin P do
(2)	← Calculate the value of membrane mi to the [(1 − NoF) + 1]-th objective function;
(3)	← Calculate the value of membrane mi to the (NoF + 1)-th objective function;
(4)	for i = 1 to N do
(5)	← ;
(6)	ifthen
(7)	Pi(i) = 1;
(8)	else
(9)	Pi(i) = [0.95 + 0.05  (/0.01)]  Pi(i);
(10)	IP ← ;
(11)	for each m in P do
(12)	if The epsilon vector is permutation of (1, 0, …, 0) then
(13)	IP ← IP  m;
(14)	Select membranes using binary tournament selection from P and add them to IP;
(15)	return IP;
