Adaptive Variable Neighborhood Search-Based Supply Network Reconfiguration for Robustness Enhancement

Algorithm 2

Solution initialization.

	Input: G = (, E), Role, K and Ninitial
	Output: S
	POP = ∅;
	fori = 1: Ninitial
	Si ⟵ Generate a solution randomly;
	if Si is different from any solutions in POP;
	Add Si into POP;
	else
	Modify Si and add it into POP;
	end if
	end for
	evaluate solution Si according to fitness function;
	//Identify the best solution Sb in the POP;
	b = argmaxi∈(1, 2,…,Ninitial) fitness (Si);
	S ⟵ Sb;
	returnS
