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

Algorithm 8

Fusion.

	Input: o (the newly generated membrane), (upper bound vectors), NoF (the mark of main objective function), B (neighbor membrane matrix)
	Output: o, B (the updated neighbor membrane matrix)
(1)	← Calculate the value of membrane o to the (NoF + 1)-th objective function;
(2)	for l = 1 to N do
(3)	;
(4)	ifthen
(5)	;
(6)	k ← ;
(7)	Remove the upper bound vector of membrane o;
(8)	Duplicate the upper bound vector in environment, and add it to membrane o;
(9)	for each mi in B(o) do
(10)	← Calculate the value of membrane mi to the (NoF + 1)-th objective function;
(11)	;
(12)	ifthen
(13)	;
(14)	;
(15)	ifthen
(16)	;
(17)	ifthen
(18)	Remove the decision variables of membrane mi;
(19)	Duplicate the decision variables of membrane o and add them to membrane mi;
(20)	return o and B;
