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

Algorithm 9

Cytolysis and Selection.

	Input: o (the newly generated membrane), EM (the external archive membrane)
	Output: EM (the updated external archive membrane)
(1)	isDominated ← false;
(2)	[o_F1, o_F2] ← Calculate the objective function values of membrane o;
(3)	for each m in EM do
(4)	[m_F1, m_F2] ← Calculate the objective function values of membrane m;
(5)	if o dominate m then
(6)	Remove membrane m in EM;
(7)	if m dominate o then
(8)	isDominated ← true;
(9)	if o_F1 =  = m_F1 && o_F2 =  = m_F2 then
(10)	isDominated ← true;
(11)	if isDominated is true then
(12)	Add membrane o to EM;
(13)	return EM;
